Riemann was a master at applying this principle and also the first who noticed and emphasized that a meromorphic function is determined by its 'singularities'.

Amazing and mysterious for our cognition is the role of Euclidean space. Even today many philosophers believe (following Kant) that 'real space' is Euclidean and other spaces being 'abstract constructs of mathematicians, should not be called spaces'. The thesis is no longer tenable - the whole of physics testifies to that. Nevertheless, there is a grain of truth in the 3 'prejudice': E (three-dimensional Euclidean space) is special in a particular way pleasantly familiar to us - in it we (also we mathematicians!) feel particularly 'confident' and move with a sense of greater 'safety' than in non-Euclidean spaces. For this reason perhaps, Riemann space M stands out among the multitude of 'interesting geometries'. For it is: 1. Locally Euclidean, i. e. , M is a differentiable manifold whose tangent spaces TxM are equipped with Euclidean metric Uxi 2. Every submanifold M of Euclidean space E is equipped with Riemann natural metric (inherited from the metric of E) and it is well known how often such submanifolds are used in mechanics (e. g. , the spherical pendulum).

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Noun Phrases and Nominalizations: The Syntax of DPs is a theoretical study of nominal expressions which covers central aspects of their syntax that have not been approached with concurrent tools in recent years. The study examines the functional structure, offers a structural definition of syntactic nominalization, and carefully draws the border line between the lexical nominalizing mechanism and its syntactic counterpart. The empirical base of the study is broad and varied: it explores the rich nominal system of Modern Hebrew with constant comparisons to relevant structures of other Semitic and non-Semitic languages. The analyses put forward have recourse to a minimal syntactic apparatus, thus lending support to Chomsky's recent view of language design. This book targets researchers in theoretical linguistics and comparative syntax. Alongside theoretical and cross-linguistic findings, the book also offers an abundant source of insights into Hebrew nominal expressions. It can be used both as a foundational book on the syntax of nominal expressions or as a reference book for linguists and graduate students of Semitic and comparative syntax. 236 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For many practical problems, observations are not independent. In this book, limit behaviour of an important kind of dependent random variables, the so-called mixing random variables, is studied. Many profound results are given, which cover recent developments in this subject, such as basic properties of mixing variables, powerful probability and moment inequalities, weak convergence and strong convergence (approximation), limit behaviour of some statistics with a mixing sample, and many useful tools are provided. Audience: This volume will be of interest to researchers and graduate students in the field of probability and statistics, whose work involves dependent data (variables). 446 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Plessy v Ferguson (1897) established racial segregation in American constitutional law for over fifty years and its moral and political legacy lives on, despite attempts in the United States to counter its devastating effects during the last half century. Ironically, in the current debate over affirmative action, Justice Harlan's eloquent dissent has been used to justify attacks on government affirmative action programs. In this book, five distinguished philosophers and constitutional theorists, working from very different theoretical positions, take a fresh critical look at the moral and political principles underlying this historic decision and Harlan's dissent. They also explore the nature and extent of law's complicity in perpetuating Plessy's racialist aims. Emerging from their varied but complementary analyses is a deeper and more nuanced understanding of the social injustice of racial segregation in its historic and contemporary forms and of resources of the law to reverse it. 120 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -All former Soviet Union countries experience their past as a heavy burden. It led to the centralisation of scientific personnel, the separation of research from teaching at universities, and a concentration of certain branches of technology in different parts of the Union. This has given rise to a one-sided technology and science potential which frequently cannot be sufficiently supported due to a lack of adequate finance.Cooperation between the Baltic States themselves is often hampered by an exaggerated sense of national identity, and international cooperation can be made difficult by linguistic problems. A critical issue is finance. The Baltic States themselves are experiencing budgetary constraints, and the West is cutting back on funding.The analytical issues dealt with here include specific questions, such as in the sectors of energy policy, electrical equipment and electronics, and environmental considerations. The transfer of technology is also discussed, as is security: there is the possibility that science and scientific results can be obtained from the former Soviet Union at low cost by the criminal community.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This Symposium began with a proposal for a meeting to honour Emer itus Professor Robert Hanbury Brown on the occasion of his 80th birthday. He requested that any such meeting should be on a topic that would be of benefit to the Sydney University Stellar Interferometer (SUSI) program. With SUSI and several other high angular resolution instruments either in operation or coming on line within the next decade, and with advances in astrometry, spectroscopy and in theoretical models of stellar atmospheres and interiors, it appeared to be both appropriate and timely to hold a symposium on 'Fundamental Stellar Properties: the Interaction between Observation and Theory. ' The emphasis of the meeting was on the critical assessment of the qual ity, accuracy, and prospects for improvement of the observational data and theoretical models, on the outstanding problems in stellar astrophysics, and on the feasibility of achieving the observational and theoretical advances required for their solution. Invited papers comprised the major part of the oral program and the speakers responded to the challenge issued by the Scientific Organising Committee to critically review the current status and prospects for their area of expertise. The Symposium was opened by the Chancellor of the University of Sydney, Emeritus Professor Dame Leonie Kramer, who welcomed the 126 participants from 22 countries on behalf of the University. The oral program included . 52 invited reviews and papers and 10 contributed papers. 512 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of operator algebras acting on a Hilbert space was initiated in thirties by papers of Murray and von Neumann. In these papers they have studied the structure of algebras which later were called von Neu mann algebras or W\* -algebras. They are weakly closed complex \*-algebras of operators on a Hilbert space. At present the theory of von Neumann algebras is a deeply developed theory with various applications. In the framework of von Neumann algebras theory the study of fac tors (i.e. W\* -algebras with trivial centres) is very important, since they are comparatively simple and investigation of general W\* -algebras can be reduced to the case of factors. Therefore the theory of factors is one of the main tools in the structure theory of von Neumann algebras. In the middle of sixtieth Topping [To 1] and Stormer [S 2] have ini tiated the study of Jordan (non associative and real) analogues of von Neumann algebras - so called JW-algebras, i.e. real linear spaces of self adjoint opera.tors on a complex Hilbert space, which contain the identity operator 1. closed with respect to the Jordan (i.e. symmetrised) product INTRODUCTION 2 x 0 y = ~(Xy + yx) and closed in the weak operator topology. The structure of these algebras has happened to be close to the struc ture of von Neumann algebras and it was possible to apply ideas and meth ods similar to von Neumann algebras theory in the study of JW-algebras. 244 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hitherto the disposal of munitions was mostly concerned with obsolete stocks, but the political developments in the states of the former Soviet Union have necessitated the disposal of vast quantities of current and obsolete stocks. Obviously, open burning/open detonation cannot be used on such a large scale, not least for environmental considerations. There are two main technical problems associated with the disposal of munitions on the scale required. First, the materials are not simple wastes or rubbish. Their handling, storage, packaging and transportation are subject to very rigid regulation, and justifiably so, for obvious reasons. Second, they are very valuable goods, for which a high price has been paid by the holding states' economic systems. Mere destruction would mean the irretrievable loss of the value invested. But therein lies the problem. Goods like steel or brass scrap can easily be reclaimed, but hypergols and other rocket fuels (for instance) represent a true chemical challenge, while, under certain conditions, explosives may be diverted to civilian use. This, in summary, is the problem that the present book deals with: the two-pronged attack involving demilitarization and recycling technologies. 168 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of the NATO Advanced Research Workshop on 'Atomic and Molecular Wires'. It was sponsored by the Ministry of Scientific Affairs Division special program on Nanoscale Science with the support of the CNRS and the Max Planck Institute. Scientists working or interested in the properties of wires at a subnanoscale were brought together in Les Houches (France) from 6 to 10 May 1996. Subnanoscale wires can be fabricated either by surface physicists (atomic wires) or by synthetic chemists (molecular wires). Both communities present their foremost advances using, for example, STM to assemble atomic lines atom for atom, to fabricate a mask for such a line or using the wide range of chemical synthesis techniques to obtain long, rigid and conjugated oligomers. Interconnecting such tiny wires to sources (voltage, current) continues to demand a great technological effort. But nanolithography associated with microfabrication or STM are now clearly identified paths for measuring the electrical resistance of an atomic or a molecular wire. The first measurements have been reported on Xe , benzene, C ' di(phenylene-ethynylene) showing 2 60 the need for a deeper understanding of transport phenomena through subnanowires. Such transport phenomena like tunnel (off-resonance) transport and Coulomb blockade have been discussed by theorists with an emphasis on the exponential decrease of the tunnel current with the wire length versus the ballistic regime of transport. 248 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides a unique, in-depth view of past, present and potential future climatic change in mountain regions, and in particular on the mechanisms which are responsible for this change. Other books which focus on environmental change in mountains focus more generally on the impacts of this change on mountain systems, rather than on the regional features of climatic change itself. The book enters into a high level of detail concerning results of international investigations which involve specialists from numerous climate-related disciplines. The book can be used in an academic and research context, for advanced graduate and doctoral students, as well as researchers working in various domains of relevance to climatic change issues. The book also has relevance in the context of future activities of the Intergovernmental Panel on Climate Change (IPCC), in terms of providing up-to-date knowledge of fundamental mechanisms and consequences of climatic change in mountain regions. 308 pp. Englisch.

Neuware -On behalf of the Russian Federation Committee on Water Economy, I would like to welcome the participants of the NATO-sponsored Workshop on the Problems of the Caspian Sea and the Circum-Caspian States. The world's largest intercontinental sea/lake is well known for its wealth mineral and fuel resources and sturgeon stocks' the products of which (oil and caviar) are in constant demand on the world market. During the last half-century the Caspian Sea has been the focus of the scientific community concerned with its level fluctuations. We were, and still are, solving a two-faceted issue: to rescue the Caspian Sea and to rescue the population from the Caspian Sea. To rescue the Caspian Sea is to address a broad spectrum of environmental issues related primarily to water pollution by waste water and petroleum products. To rescue the population from the Caspian Sea means that an almost 2.5 m sea level rise in the last two decades has resulted in flooding of vast coastal areas deteriorating economic and social spheres of activity. Solutions to these issues are linked to the numerous mysterious aspects of recent Caspian Sea behavior. Regrettably, the collapse of the USSR has led to a decline of marine observations and control over the use of marine resources in the region. Coordinated international action on the protection of living marine resources have terminated, generating disastrous consequences.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 334 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Many dynamical systems are described by differential equations that can be separated into one part, containing linear terms with constant coefficients, and a second part, relatively small compared with the first, containing nonlinear terms. Such a system is said to be weakly nonlinear. The small terms rendering the system nonlinear are referred to as perturbations. A weakly nonlinear system is called quasi-linear and is governed by quasi-linear differential equations. We will be interested in systems that reduce to harmonic oscillators in the absence of perturbations. This book is devoted primarily to applied asymptotic methods in nonlinear oscillations which are associated with the names of N. M. Krylov, N. N. Bogoli ubov and Yu. A. Mitropolskii. The advantages of the present methods are their simplicity, especially for computing higher approximations, and their applicability to a large class of quasi-linear problems. In this book, we confine ourselves basi cally to the scheme proposed by Krylov, Bogoliubov as stated in the monographs [6,211. We use these methods, and also develop and improve them for solving new problems and new classes of nonlinear differential equations. Although these methods have many applications in Mechanics, Physics and Technique, we will illustrate them only with examples which clearly show their strength and which are themselves of great interest. A certain amount of more advanced material has also been included, making the book suitable for a senior elective or a beginning graduate course on nonlinear oscillations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Cambridge Platonists were defenders of tolerance in the political as well as the moral sphere ; they held that practical j u d g e m e n t came down in the last instance to individual conscience ; and they laid the foundations of our modern conceptions of conscience and liberty. But at the same time they ma intained the existence of eternal truths , and of a Good-in-itself , identical with Truth and Being, refusing to admit that freedom of conscience i m p li e d moral relativism. They were critics of dogmatism, and of the sectarian notion of 'enthusiasm' as a source of illumination , on the grounds that both were disruptive of social harmony; they pleaded the cause of reason , in the hope that it could become the foundation of all human knowledge . Yet , for all that , they ma intained that a certain sort of mystical illumination lay at the heart of all true thought , and that human reason had validity only in virtue of i t s divine origin . They debated with Des cartes and took a keen interest in his mech- ism and his dualism ; they brought the atomistic theories of Democritus back into repute; and they sought to provide a detailed account of the causality link ing all phenomena. 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Workshop on Physics and Application of Non-crystalline Semiconductors in Optoelectronics was held from 15 to 17 October 1996 in Chisinau. republic of Moldova and was devoted to the problems of non-crystalline semiconducting materials. The reports covered two mjlin topics: theoretical basis of physics of non -crystalline materials and experimental results. In the framework of these major topics there were treated many subjects. concerning the physics of non-crystalline semiconductors and their specific application: -optical properties of non-crystalline semiconductors; -doping of glassy semiconductors and photoinduced effects in chalcogenide glasses and their application for practical purposes; -methods for investigation of the structure in non-crystalline semiconductors -new glassy materials for IR trasmittance and optoelectronics. Reports and communications were presented on various aspects of the theory. new physical principles. studies of the atomic structure. search and development of optoelectronics devices. Special attention was paid to the actual subject of photoinduced transformations and its applications. Experimental investigations covered a rather wide spectrum of materials and physical phenomena. As a novel item it is worth to mention the study of nonlinear optical effects in amorphous semiconducting films. The third order optical non linearities. fast photoinduced optical absorption and refraction. acusto-optic effects recently discovered in non-crystalline semiconductors could potentially be utilised for optical signal processing. The important problems of photoinduced structural transformations and related phenomena. which are very attractive and actual both from the scientific and practical points of view. received much attention in discussions at the conference. 498 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The NATO Advanced Research Workshop (ARW) on 'Regulation of Enzymatic Systems Detoxifying Xenobiotics in Plants' intended to provide a forum to scientists from academia, industry, and govemment for discussing and critically assessing recent advances in the field of xenobiotic metabolism in plants and for identifying new directions for future research. Plants function in a chemical environment made up of nutrients and xenobiotics. Xenobiotics (foreign chemicals) are natural or synthetic compounds that can not be utilized by plants for energy-yielding metabolism. Plants may be exposed to xenobiotics either deliberately, due to their use as pesticides or accidentally, from industrial, agricultural, and other uses. Plants, like most other organisms, evolved a remarkable battery or metabolic reactions to defend themselves against the potentially toxic effects of xenobiotics. The main enzymatic reactions utilized by plants for xenobiotic detoxification include oxidation, reduction, hydrolysis and conjugation with glutathione, sugars (e.g., glucose), and amino acids. Eventually, xenobiotic conjugates are converted to insoluble bound residues or to secondary conjugates, which are deposited in the vacuole of plant cells. 404 pp. Englisch.
