Taschenbuch. Condizione: Neu. Neuware -During the past decade there has been a dramatic change in the nature of mobile communications technology and its impact on the general communic ations environment. In the 1970s, mobile radio was a minority activity in communications, based on relatively unsophisticated technology. The 1980s, however, have seen the emergence of analogue cellular systems and the definition of future digital systems, and the predicted demand for these services is such that investigations into the use of higher frequency bands have already begun. It is predicted that, by the late 1990s, the 'personal communications' world will have resulted in the majority of adults in Europe and North America being dependent on radio-connected terminals of various kinds for more than 50% of their total telecommunications needs. The technology which will form the basis of this revolution has now been defined, at least in outline, and the fixed and mobile equipment that will be used in systems of the future will bear little resemblance to that available even ten years ago. It is impossible within the confines of a single, relatively short book to cover all the subject areas needed for a study of this exciting and expanding field of technology. We have, perforce, been selective and have chosen those topics which we believe to be of primary importance at the present time.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - The delivery of modern nursing care is essentially a team effort, that is a team whose individuals co-operate with one another to achieve high standards. This book, drawing on the expertise of successful nurse managers, a nurse educator and a management lecturer, provides the reader with 'tools' to enable him or her review and develop their 'people-management' skills. The 'tools' are in the form of exercises and activities designed to help the reader apply theory to practice and to take the learning back to the work-place. Topics covered in Managing People include leadership, team building, creating a learning climate and monitoring performance.

Taschenbuch. Condizione: Neu. Neuware -This monograph is a systematic exposition of the authors' research on general equi librium models with an infinite number of commodities. It is intended to serve both as a graduate text on aspects of general equilibrium theory and as an introduction, for economists and mathematicians working in mathematical economics, to current research in a frontier area of general equilibrium theory. To this end, we have pro vided two introductory chapters on the basic economic model and the mathematical framework. The exercises at the end of each section complement the main exposition. Chapter one is a concise but substantiative discussion of the questions of exis tence and optimality of competitive equilibria in the Walrasian general equilibrium model of an economy with a finite number of households, firms and commodities. Our extension of this model to economies with an infinite number of commodities constitutes the core material of this book and begins in chapter three. Readers fa miliar with the Walrasian general equilibrium model as exposited in [13], [23J or [52J may treat chapter one as a handy reference for the main economic concepts and notions that are used throughout the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -During the last four decades remarkable developments have taken place in instrumentation and techniques for characterizing the microstructure and microcomposition of materials. Some of the most important of these instruments involve the use of electron beams because of the wealth of information that can be obtained from the interaction of electron beams with matter. The principal instruments include the scanning electron microscope, electron probe x-ray microanalyzer, and the analytical transmission electron microscope. The training of students to use these instruments and to apply the new techniques that are possible with them is an important function, which. has been carried out by formal classes in universities and colleges and by special summer courses such as the ones offered for the past 19 years at Lehigh University. Laboratory work, which should be an integral part of such courses, is often hindered by the lack of a suitable laboratory workbook. While laboratory workbooks for transmission electron microscopy have-been in existence for many years, the broad range of topics that must be dealt with in scanning electron microscopy and microanalysis has made it difficult for instructors to devise meaningful experiments. The present workbook provides a series of fundamental experiments to aid in 'hands-on' learning of the use of the instrumentation and the techniques. It is written by a group of eminently qualified scientists and educators. The importance of hands-on learning cannot be overemphasized.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -With the growing recognition during the last two centuries that the Earth has an immense age and processes over long periods of time have changed the morphology and composition of the Earth's crust, geologists have become increasingly interested in determination of absolute ages. A rela tive geochronology was established on the basis of the lithostratigraphic and biostratigraphic principles developed during the last century. With the discovery of radioactivity, the basis for a new geoscientific discipline - geochronology - was established (Rutherford 1906). It is the study of geological time, based mainly on the time signatures provided by the isotopic composition in geologic materials. The isotopic signature in a rock yields more information than that provided by the geochemical signature alone because it reflects the origin and history of the element in the rock. The aim of geochronology is to calibrate and standardize chronostrati graphic scales, to develop geological time scales that have a sensitive or at least useful resolution in order to place the geological events in the correct chronological order, and to assign their proper time spans. In practice, the application of geochronology is much wider because the data in the 'natural archives' often provide information on the origin, genesis, and history of the materials. This, of course, requires an understanding of the geochemical behavior of the substances involved.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 520 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is clear that child and adolescent psychiatric disorders impose a heavy burden of suffering. Recent large-scale community epidemiological studies suggest that as many as 20% of children and adolescents in the general population may have clinically important mental disorders. These disorders are accompanied by associated impairments in various domains of the child's life, resulting in lowered life quality for the child and his or her family. In addition, for some conditions, the onset of the disorder in childhood heralds a lifetime of serious psychosocial disturbance for a significant subgroup of affected children. For instance, about 40% of children seen in clinic settings with conduct disorder in late childhood and early adolescence will have serious psychiatric disorders in adult life. Finally, the heavy burden of suffering of these conditions is indicated by the large amounts of both human and financial resources devoted to their assessment and treatment. There is a pressing need in the field for effective treatments (that is, those that have been shown to do more good than harm) that will result in a significant reduction in the burden of suffering resulting from these disorders. Further, these effective interventions must be readily available and acceptable to clini cians in the settings in which children with mental disorders (and their families) seek care. This book addresses an important need in the treatment field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Buch. Condizione: Neu. Neuware -Georges Enderle Before presenting some introductory remarks on the topic of this volume I should like to outline briefly the context from which this selection of articles originates. (It seems to me necessary to emphasise these circumstances in order to make clearer the contours of what is said and what is not said and to understand it better. ) This context involves, flrstly, a general evaluation of the state of the business ethics debate today and, secondly, considerations of the question of what attitude and strategy should be chosen in order to promote business ethics most effectively. On the present state of affairs of the business ethics debate Today, it is extremely difflcult, if not impossible, to gain even a rough overview of the business ethics debate in the different countries of Europe and North America. Many activities take place in informal circles and on a local and regional level; linguistic and other barriers impede the spread of information about them and, often, they are not even labelled 'business ethics'. At the same time, so many other things sail under the flag of 'business ethics' that one sometimes wonders if it should not be replaced by another flag, for instance new methods of public-relations or better motivation of company's employees. Yet, in spite of these difflculties in deflning business ethics activities, one statement at least can be made with certainty.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condizione: Neu. Neuware -Tadeusz Kotarbinski is one of towering figures in contemporary Polish philosophy. He was a great thinker, a great teacher, a great organizer of philosophical and scientific life (he was, among others, the rector of the Uni versi ty of t6dz, the president of the Polish Academy of Sciences, and the president of the International Institute of Philosophy), and, last but not least, a great moral authority. He died at the age of 96 on October 3, 1981. Kotarbinski was active in almost all branches of philosophy. He made many significant contributions to logic, semantics, ontology, epistemology, history of philosophy, and ethics. He created a new field, namely praxiology. Thus, using an ancient distinction, he contributed to theoretical as well as practical philoso~hy. Kotarbinski regarded praxiology as his major philosophical 'child'. Doubtless, praxiology belongs to practical philosophy. This collection, howewer, is mainly devoted to Kotarbinski' s theoretical philosophy. Reism - Kotarbinski' s fundamental idea of ontology and semantics - is the central topic of most papers included here; even Pszczolowski' s essay on praxiology considers its ontological basis. ,Only two papers, namely that of Zarnecka-Bialy and that of Wolenski, are not linked with reism. However, both fall under the general label 'Kotarbinski: logic, semantics and ontology'. The collection partly consists of earlier published papers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book presents theories and techniques for perception of textures by computer. Texture is a homogeneous visual pattern that we perceive in surfaces of objects such as textiles, tree barks or stones. Texture analysis is one of the first important steps in computer vision since texture provides important cues to recognize real-world objects. A major part of the book is devoted to two-dimensional analysis of texture patterns by extracting statistical and structural features. It also deals with the shape-from-texture problem which addresses recovery of the three-dimensional surface shapes based on the geometry of projection of the surface texture to the image plane. Perception is still largely mysterious. Realizing a computer vision system that can work in the real world requires more research and ex periment. Capability of textural perception is a key component. We hope this book will contribute to the advancement of computer vision toward robust, useful systems. vVe would like to express our appreciation to Professor Takeo Kanade at Carnegie Mellon University for his encouragement and help in writing this book; to the members of Computer Vision Section at Electrotechni cal Laboratory for providing an excellent research environment; and to Carl W. Harris at Kluwer Academic Publishers for his help in preparing the manuscript.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 190 pp. Englisch.

Griffiths (Department ofManufacturing and Engineering Systems, BruneI University, Uxbridge, Middlesex, UK) To create, to engineer, to err and to destroy are basic human traits. Human progress depends upon the balanced exploitation of some of these traits. Our quality and standards of living are closely intertwined with the effective management ofsome of these traits and the limited physical resources that are at our disposal. The only sensible approach to harmonize and blend these two spheres is to effectively monitor, diagnose and control our own actions and reactions, at every stage. We are now privileged to live in an age of advanced technology which is significantly influencing the basic infrastructures of our societies, on which our lives nowdepend. The rapid rate atwhichthe technological changesarespreading is causing much confusion and uncertainty in communities, governments and industries at different levels. This, in tum, is creating and widening gaps and mismatches of unknown dimensions in almost all human endeavours. Such undesirable tendencies mustbe monitored, diagnosed, prognosed and controlled with the utmost haste and urgency. 508 pp. Englisch.

Buch. Condizione: Neu. Neuware -The growth of knowledge and its effects on the practice of medicine have been issues of philosophical and ethical interest for several decades and will remain so for many years to come. The outline of the present volume was conceived nearly three years ago. In 1987, a conference on this theme was held in Maastricht, the Netherlands, on the occasion of the founding of the European Society for Philosophy of Medicine and Health Care (ESPMH). Most of the chapters of this book are derived from papers presented at that meeting, and for the purpose of editing the book Stuart Spicker, Ph. D. , joined two founding members of ESPMH, Henk ten Have and Gerrit Kimsma. The three of them successfully brought together a number of interesting contribu tions to the theme, and ESPMH is grateful and proud to have initiated the production of this volume. The Society intends that annual meetings be held in different European countries on a rotating basis and to publish volumes related to these meetings whenever feasible. In 1988, the second conference was held in Aarhus, Denmark on 'Values in Medical Decision Making and Resource Allocation in Health Care'. In 1989, a meeting was held in Czestochowa, Poland, on 'European Traditions in Philosophy of Medicine. From Brentano to Bieganski'. It is hoped that these conferences and the books to be derived from them, will initiate a new European tradition, lasting well into the 21 st century! P.

Buch. Condizione: Neu. Neuware -may be complex without being able to be replaced by something »still more simple«. This became evident with the help of computer models of deterministic-recursive systems in which simple mathematical equation systems provide an extremely complex behavior. (2) Irregularity of nature is not treated as an anomaly but becomes the focus of research and thus is declared to be normal. One looks for regularity within irregularity. Non-equilibrium processes are recognized as the source of order and the search for equilibrium is replaced by the search for the dynamics of processes. (3) The classical system-environment model, according to which the adaptation of a system to its environment is controlled externally and according to which the adaptation of the system occurs in the course of a learning process, is replaced by a model of systemic closure. This closure is operational in so far as the effects produced by the system are the causes for the maintenance of systemic organization. If there is sufficient complexity, the systems perform internal self-observation and exert self-control (»Cognition« as understood by Maturana as self-perception and self-limitation, e. g. , that of a cell vis-a. -vis its environment). 22 But any information a system provides on its environment is a system-internal construct. The »reference to the other« is merely a special case of »self-reference«. The social sciences frequently have suffered from the careless way in which scientific ideas and models have been transferred.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -Wittgenstein's aphoristic style holds great charm, but also a great danger: the reader is apt to glean too much from a single fragment and too little from the fragments as a whole. In my first confron tations with the Philosophical Investigations I was such a reader, and so, it turned out, were most of the writers on Wittgenstein's later philosophy. Wittgenstein's remarkable ability to bring together many facets of his thought in one fragment is fully exploited in the critical literature; but hardly any attention is paid to the connection with other fragments, let alone to the many hitherto unpublished manuscripts of which the Philosophical Investigations is the final product. The result of this fragmentary and ahistorical approach to Wittgenstein's later work is a host of contradictory interpretations. What Wittgenstein really wanted to say remains insufficiently clear. Opinions are also strongly divided about the value of his work. Some authors have been encouraged by his aphorisms and rhetorical questions to dismiss the whole Cartesian tradition or to halt new movements in linguistics or psychology; others, exasperated, reject his philo sophy as anti-scientific conceptual conservatism. After consulting unpublished not Elektronisches Buch and manuscripts which Wittgenstein wrote between 1929 and 1951, I became a very different reader. Wittgenstein turned out to be a kind of Leonardo da Vinci, who pursued a form from which every sign of chisel ling, every attempt at improvement, had been effaced.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Contemporary Systems Thinking is a series of texts, each of which deals comparatively and/or critically with different aspects of holistic thinking at the frontiers of the discipline. Traditionally, writings by systems thinkers have been concerned with single theme propositions such as General Systems Theory, Cybernetics, Operations Research, System Dynamics, Soft Systems Methodology and many others. Recently there have been attempts to fulfil a different yet equally important role by comparative analyses of viewpoints and approaches, each addressing disparate areas of study such as: modeling and simulation, measurement, management, 'problem solving' methods, international relations, social theory and last, but not exhaustively or least, philosophy. In a recent book these were drawn together within a multiform framework as part of an eclectic discussion -a nearly impossible task as I discovered (see Dealing With Complexity -An Introduction to the Theory and Application of Systems Science, R. L. Flood and E. R. Carson, Plenum, New York, 1988). Nevertheless, bringing many sources together led to several achievements, among which was showing a great diversity of approaches, ideas and application areas that systems thinking contributes to (although often with difficulties remaining unresolved). More important, however, while working on that manuscript I became aware of the need for and potential value in a series of books, each focusing in detail on the study areas mentioned above.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 270 pp. Englisch.

Buch. Condizione: Neu. Neuware -Preface This book is the culmination of a workshop jointly organized by NATO and CEC on Climate-Ocean Interaction which was held at Lady Margaret Hall, Oxford University during 26-30 September 1988. The objective of the ARW was to assess the current status of research on climate-ocean interaction, with a major focus on the development of coupled atmosphere-ocean-ice models and their application in the study of past, present and possible future climates. This book contains 16 chapters divided into four parts: Introduction; Observations of the Climate of the Ocean; Modelling the Atmospheric, Oceanic and Sea Ice Components of the Climatic System; and Simulating the Variability of Climate on Short, Medium and Long Time Scales. A fifth part contains the reports of the five Working Groups on: Climate Observations, Modelling, ENSO Modelling and Prediction, Climate-Ocean Interaction on TIme Scales of Decades to Centuries, and Impact of Paleoclimatic Proxy Data on Climate Modelling. Preface ix Acknowledgements I thank Howard Cattle and Neil Wells for their guidance and assistance as members of the Workshop Organizing Committee. I particularly thank Michael Davey for all his efforts as Local Organizer to make the ARW a success. I also thank the staff of Lady Margaret Hall, Oxford University, for their help with the arrangements for the ARW.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 406 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book is the definitive reference on phase-transfer catalysis (PTC), written by the three foremost industrial and academic PTC experts in the world. Phase-Transfer Catalysis, the first practical guide to performing PTC in industry, includes key information and analyses found in no other publication. It will be a valuable resource for synthetic organic chemists, polymer chemists, process chemists, developmental chemists, and chemical engineers in academia and industry. Organic process chemists seeking greater process flexibility, reduced manufacturing costs and pollution, and easier compliance with environmental regulations will find it an indespensable reference. The book provides a thorough introduction to the fundamentals of PTC as a synthetic organic chemistry technique, including reaction mechanisms, selectivity, rates and kinetics. It gives specific guidelines on how to optimize catalyst, solvent, base, hydration, and more, based on reaction characteristics. The section on applications includes nucleophilic displacement reactions, oxidation and reduction reactions, and such special topics as insoluble PTC (triphase catalysis), polymerization, chiral catalysis, applications in environmental and analytical chemistry, and transition metal co-catalyzed PTC. Throughout the book, PTC applications in key industries are discussed--including organic chemicals, polymers, pharmaceuticals, agrichemicals, monomers, petrochemicals, flavors and fragrances, additives, dyes, and specialty chemicals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 462 pp. Englisch.

Buch. Condizione: Neu. Neuware -There are many reasons for writing a book; this one was conceived and devel oped mainly for two. First, a new area has emerged from within the forensic sciences-that of forensic phonetics. As with all new specialties, it is necessary to define it, identify its boundaries, justify its importance and compile a list of the elements it encompasses. This book attempts to outline these several rela tionships. Second, over the past decade I have become fascinated with forensics in general and the rapidly expanded subarea of forensic phonetics in particular. Admittedly, the latter field is one that is not as yet sufficiently appreciated-and much more needs to be known about its nature and extent. Yet, I have found it to be a most enjoyable area of study and my attempts to describe its domains were quite informative. It was especially interesting to struggle with the interfaces between forensic phonetics and related fields, and discover how they overlap. Only a few comments will be made about the book's contents here in the preface. For one thing, they are described in some detail in the first chapter.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Buch. Condizione: Neu. Neuware -The purpose of this book is to introduce and explain research at the boundary between two fields that view problem solving from different perspectives. Researchers in operations research and artificial intelligence have traditionally remained separate in their activities. Recently, there has been an explosion of work at the border of the two fields, as members of both communities seek to leverage their activities and resolve problems that remain intractable to pure operations research or artificial intelligence techniques. This book presents representative results from this current flurry of activity and provides insights into promising directions for continued exploration. This book should be of special interest to researchers in artificial intelligence and operations research because it exposes a number of applications and techniques, which have benefited from the integration of problem solving strategies. Even researchers working on different applications or with different techniques can benefit from the descriptions contained here, because they provide insight into effective methods for combining approaches from the two fields. Additionally, researchers in both communities will find a wealth of pointers to challenging new problems and potential opportunities that exist at the interface between operations research and artificial intelligence. In addition to the obvious interest the book should have for members of the operations research and artificial intelligence communities, the papers here are also relevant to members of other research communities and development activities that can benefit from improvements to fundamental problem solving approaches.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 526 pp. Englisch.

Buch. Condizione: Neu. Neuware -This ENCYCLOPAEDIA OF MATHEMATICS aims to be a reference work for all parts of mathe matics. It is a translation with updates and editorial comments of the Soviet Mathematical Encyclopaedia published by 'Soviet Encyclopaedia Publishing House' in five volumes in 1977-1985. The annotated translation consists of ten volumes including a special index volume. There are three kinds of articles in this ENCYCLOPAEDIA. First of all there are survey-type articles dealing with the various main directions in mathematics (where a rather fine subdivi sion has been used). The main requirement for these articles has been that they should give a reasonably complete up-to-date account of the current state of affairs in these areas and that they should be maximally accessible. On the whole, these articles should be understandable to mathematics students in their first specialization years, to graduates from other mathematical areas and, depending on the specific subject, to specialists in other domains of science, en gineers and teachers of mathematics. These articles treat their material at a fairly general level and aim to give an idea of the kind of problems, techniques and concepts involved in the area in question. They also contain background and motivation rather than precise statements of precise theorems with detailed definitions and technical details on how to carry out proofs and constructions. The second kind of article, of medium length, contains more detailed concrete problems, results and techniques. 560 pp. Englisch.

Buch. Condizione: Neu. Neuware -THIS BOOK collects together papers given at a NATO Advanced Research Workshop held at Il Ciocco (Lucca), Italy, from the 9th to the 15th April, 1989. It sets out to present the current state of understanding of the principles governing the way fluxes and concentrations are maintained and controlled in metabolic systems. Although this is a topic that has held the interest of biochemists for many years, it is only quite recently that the methods of analysing the kinetics of multi-enzyme pathways developed over the past two decades have come to be widely discussed or applied experimentally. Many biochemists remain sceptical that the new methods offer a real advance (except in complexity) over the landmark discoveries of the 1950s and 1960s relating to inhibition of enzymes at branch-points by the end products of metabolic pathways, and the interpretation of allosteric effects and cooperativity. Even those who have become convinced that the classical ideas provide only the starting point for understanding metabolic control have been by no means unanimous in their assess ment of the direction in which one should advance. In this book we have tried to include all of the current points of view, including the view that the classical theories tell us all that we need to know. We have not seen it as our role as editors to paper over the cracks that exist and to pretend that we can speak to the world with one voice. 472 pp. Englisch.

Buch. Condizione: Neu. Neuware - This second volume in the new series produced by the Mineralogical Society is concerned with the study of rocks from the deep continental crust. It is, we hope, timely to summarize recent petrological advances contributing to this field of active interest. Based mainly on review papers read at a conference, the chapters have subsequently been revised and expanded, while the editors have produced an introductory overview as Chapter 1. The conference was the Winter Meeting of the Mineralogical Society on 15 December 1988, at wh ich Prof. R. C. Newton delivered the 20th Hallimond Lecture of the Society (which forms the basis of Ch. 7). The editors are grateful to all who contrib uted to the smooth running of the meeting at Kingston Polytechnic, and in the ensuing preparation of the volume: in particular, we sincerely thank all of the following for their labours as referees: A.

Buch. Condizione: Neu. Neuware - This book is about the logic of Boolean equations. Such equations were central in the 'algebra of logic' created in 1847 by Boole [12, 13] and devel oped by others, notably Schroder [178], in the remainder of the nineteenth century. Boolean equations are also the language by which digital circuits are described today. Logicians in the twentieth century have abandoned Boole's equation based logic in favor of the more powerful predicate calculus. As a result, digital engineers-and others who use Boole's language routinely-remain largely unaware of its utility as a medium for reasoning. The aim of this book, accordingly, is to is to present a systematic outline of the logic of Boolean equations, in the hope that Boole's methods may prove useful in solving present-day problems. Two Logical Languages Logic seeks to reduce reasoning to calculation. Two main languages have been developed to achieve that object: Boole's 'algebra of logic' and the predicate calculus. Boole's approach was to represent classes (e. g. , happy creatures, things productive of pleasure) by symbols and to represent logical statements as equations to be solved. His formulation proved inadequate, however, to represent ordinary discourse. A number of nineteenth-century logicians, including Jevons [94], Poretsky [159], Schroder [178], Venn [210], and Whitehead [212, 213], sought an improved formulation based on ex tensions or modifications of Boole's algebra. These efforts met with only limited success.

Taschenbuch. Condizione: Neu. Neuware - This scientific biography of the mathematician Joseph Liouville is divided into two parts. The first part is a chronological account of Liouville's career including a description of the institutions he worked in, his relations with his teachers, colleagues and students, and the historical context of his works. It portrays the French scientific community in a period when Germany andEngland had surpassed France as the leading nations in mathematics and physics. The second part of the book gives a detailed analysis of Liouville's major contributions to mathematics and mechanics. The gradual development of Liouville's ideas, as reflected in his publications and not Elektronisches Buch, are related to the works of his predecessors and his contemporaries as well as to later developments in the field. On the basis of Liouville's unpublished notes the book reconstructs Liouville's hitherto unknown theories of stability of rotating masses of fluid, potential theory, Galois theory and electrodynamics. It also incorporates valuable added information from Liouville's notes regarding his works on differentiation of arbitrary order, integration in finite terms, Sturm-Liouville theory, transcendental numbers, doubly periodic functions, geometry and mechanics.
