Taschenbuch. Condizione: Neu. Neuware -Around 1994 R. Borcherds discovered a new type of meromorphic modular form on the orthogonal group $O(2,n)$. These 'Borcherds products' have infinite product expansions analogous to the Dedekind eta-function. They arise as multiplicative liftings of elliptic modular forms on $(SL)_2(R)$. The fact that the zeros and poles of Borcherds products are explicitly given in terms of Heegner divisors makes them interesting for geometric and arithmetic applications. In the present text the Borcherds' construction is extended to Maass wave forms and is used to study the Chern classes of Heegner divisors. A converse theorem for the lifting is proved.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book provides an approach to the study of perturbation and discretization effects on the long-time behavior of dynamical and control systems. It analyzes the impact of time and space discretizations on asymptotically stable attracting sets, attractors, asumptotically controllable sets and their respective domains of attractions and reachable sets. Combining robust stability concepts from nonlinear control theory, techniques from optimal control and differential games and methods from nonsmooth analysis, both qualitative and quantitative results are obtained and new algorithms are developed, analyzed and illustrated by examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Many introductory books on mathematical finance also outline some com puter algorithms. My goal is to contribute a closer look at algorithmic issues that arise from complex forms of the underlying pricing models-issues many practitioners need to solve sooner or later in their careers. This book takes such a close look at uncertain volatility models, an exten sion of Black-Scholes theory.It discusses applications to exotic option portfo lios with barriers and early exercise features. It describes an object-oriented C++ solution, included in source code on the accompanying CD. Practitioners and students who need to build analytic software libraries may benefit from reading this book and studying the software. The book focuses on a family of mathematical models, while in the field one encounters greater variation in instrument properties. In both cases mathematical and financial knowledge must be complemented by good programming skills to produce the best system. Analytic software needs design-a central message of the later chapters of this book. This book has come out of my Ph.D. thesis. I am very grateful to my academic advisor, Marco Avellaneda of New York University, who taught me mathematical finance and uncertain volatility. Computational finance be came exciting for me because Marco encouraged an algorithmic approach to uncertain volatility. I thank Afshin Bayrooti, Vladimir Finkelstein, and Antonio Paras for giving valuable feedback. Antonio is the co-inventor of the original uncertain volatility model, A-UVM. Richard Holmes has found a crucial bug in an early implementation of the software.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Sapere aude! Immanuel Kant (1724-1804) Numerical simulations playa key role in many areas of modern science and technology. They are necessary in particular when experiments for the underlying problem are too dangerous, too expensive or not even possible. The latter situation appears for example when relevant length scales are below the observation level. Moreover, numerical simulations are needed to control complex processes and systems. In all these cases the relevant problems may become highly complex. Hence the following issues are of vital importance for a numerical simulation: - Efficiency of the numerical solvers: Efficient and fast numerical schemes are the basis for a simulation of 'real world' problems. This becomes even more important for realtime problems where the runtime of the numerical simulation has to be of the order of the time span required by the simulated process. Without efficient solution methods the simulation of many problems is not feasible. 'Efficient' means here that the overall cost of the numerical scheme remains proportional to the degrees of freedom, i. e. , the numerical approximation is determined in linear time when the problem size grows e. g. to upgrade accuracy. Of course, as soon as the solution of large systems of equations is involved this requirement is very demanding.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -TheAdvanced Course onArti cial IntelligenceACAI2001, with the subtitle of ¿Multi- Agent Systems and Their Applications¿, held in Prague, Czech Republic, represented a joint event of ECCAI (the European Coordinating Committee for Arti cial Intel- gence) andAgentLink, the European Network of Excellence forAgent-Based Comp- ing. Whereas ECCAI organizes two-weekACAI courses on different topics each second year, AgentLink¿s European Agent Systems Summer School (EASSS) has been an - nual event since 1999. In 2001, both of these important events were merged, giving weight to the fact that multi-agent systems currently represent one of the hottest topics of AI research. The name, ACAI2001 Summer School, was intended to emphasize that this event continued the tradition of regular ECCAI activities (ACAI), as well as that of the EASSS summer schools ofAgentLink. The PragueACAI Summer School was proposed and initiated by both the Gerstner Laboratory, Czech Technical University, Prague (GL-CTU) and the Czech Society for Cybernetics and Informatics (CSKI), with the support of theAustrian Research Institute forArti cial Intelligence in Vienna (OFAI). One of the most important stimulating factors behind the organization ofACAI2001 wasthesupportprovidedbytheEuropeanCommissiontotheGerstnerLaboratorywithin the frame of the MIRACLE Centre of Excellence project (No. ICA1-CT-2000-70002). Additional support was later provided by both the Commission¿s AgentLink II project (IST-1999-29003) and ECCAI. The combined nancial and conceptual participation of these important international bodies enabled the invitation of a large number of truly world-class lecturers in this eld, who added a unique avor to the event. 396 pp. Englisch.

Buch. Condizione: Neu. Neuware -In many areas of finance and stochastics, significant advances have been made since this field of research was opened by Black, Scholes and Merton in 1973.

The topics span risk management, portfolio theory and multi-asset derivatives, market imperfections, interest-rate modelling and exotic options.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 336 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The ACM Workshop on Security and Privacy in Digital Rights Management is the rst scienti c workshop with refereed proceedings devoted solely to this topic. The workshop was held in conjunction with the Eighth ACM Conference on Computer and Communications Security (CCS-8) in Philadelphia, USA on November 5, 2001. Digital Rights Management technology is meant to provide end-to-end so- tions for the digital distribution of electronic goods. Sound security and privacy features are among the key requirements for such systems. Fifty papers were submitted to the workshop, quite a success for a rst-time workshop. From these 50 submissions, the program committee selected 15 papers for presentation at the workshop. They cover a broad area of relevant techniques, including cryptography, system architecture, and cryptanalysis of existing DRM systems. Three accepted papers are about software tamper resistance, an area about which few scienti c articles have been published before. Another paper addresses renewability of security measures. Renewability is another important security technique for DRM systems, and I hope we will see more publications about this in the future. I am particularly glad that three papers cover economic and legal aspects of digital distribution of electronic goods. Technical security measures do not exist in a vacuum and their e ectiveness interacts in a number of ways with the environment for legal enforcement. Deploying security and an- piracy measures adequately requires furthermore a good understanding of the business models that they are designed to support. 260 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of this book is to present a recently developed approach suitable for investigating a variety of qualitative aspects of order-preserving random dynamical systems and to give the background for further development of the theory. The main objects considered are equilibria and attractors. The effectiveness of this approach is demonstrated by analysing the long-time behaviour of some classes of random and stochastic ordinary differential equations which arise in many applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book addresses a subject at the crossing point of two lines of investi gation - synergetics and modern nonlinear optics. First, the book is devoted to optical patterns that previously were mainly attributed to the display of instabilities of homogeneous field distributions. Second, we deal with optical bistability and hysteresis, which historically were studied predominantly for point (lumped, spatially nondistributed) systems. In the book, which seems to be the first monograph devoted to opti cal patterns, I attempt to demonstrate that the variety of optical patterns and other synergetical phenomena is especially rich in spatially distributed bistable systems, and that instabilities of homogeneous states are not neces sary for the formation of the patterns. Of special interest are patterns such as dissipative optical solitons, which individually have particle-like features and when combined resemble molecules, crystals, biological objects, and even social groups. Another essential point is the key role of inhomogeneities of bistable sys tems. As for hysteresis, it has been studied mostly in point systems, in which, with fixed characteristics of the input signal, one of several sets of steady state output signal characteristics can form, depending on the prehistory. In spatially distributed optical systems, the kinetics of hysteresis acquires the form of 'spatial hysteresis', or hysteresis of spatial distributions of field char acteristics. This problem of 'stereoscopic vision' of such hysteresis was solved in optical bistability some 20 years ago, and the concepts proposed were later confirmed and expanded.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -Term rewriting techniques are applicable in various fields of computer sci ence: in software engineering (e.g., equationally specified abstract data types), in programming languages (e.g., functional-logic programming), in computer algebra (e.g., symbolic computations, Grabner bases), in pro gram verification (e.g., automatically proving termination of programs), in automated theorem proving (e.g., equational unification), and in algebra (e.g., Boolean algebra, group theory). In other words, term rewriting has applications in practical computer science, theoretical computer science, and mathematics. Roughly speaking, term rewriting techniques can suc cessfully be applied in areas that demand efficient methods for reasoning with equations. One of the major problems one encounters in the theory of term rewriting is the characterization of classes of rewrite systems that have a desirable property like confluence or termination. If a term rewriting system is conflu ent, then the normal form of a given term is unique. A terminating rewrite system does not permit infinite computations, that is, every computation starting from a term must end in a normal form. Therefore, in a system that is both terminating and confluent every computation leads to a result that is unique, regardless of the order in which the rewrite rules are applied. This book provides a comprehensive study of termination and confluence as well as related properties.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 436 pp. Englisch.

Buch. Condizione: Neu. Neuware -As e-commerce becomes the norm of business transactions and information be comes an essential commodity, it is vital that extensive efforts be made to examine and rectify the problems with the underlying architectures, processes, methods, that are involved in providing and and tools, as well as organizational structures, utilizing services relating to information technology. Such a holistic view of the relevant structures is required in order to identify all of the key aspects that can affect network security. Unfortunately, today's systems and practices, although they have proved to be useful and become widespread, contain significant unnecessary complexity. This complexity provides many loopholes that make systems and practices vulnerable to malicious attacks by hackers as well as by individual and organized criminals. FUrther, there are enormous risks due to malfunction of the systems. The holes in the network system cannot simply be plugged up by the use of cryptography and firewalls. While many changes need to be made in operating systems and system software with respect to security, this alone does not solve the problem. The problems cannot be solved by addressing only a single key aspect of network security. A holistic approach is required. Sumit Ghosh has provided in this book such a holistic view of the area of network security. Thus, it is a most welcome contribution.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Recent research aimed at improving the process of program construction exploits insights from abstract algebraic tools such as lattice theory, fixpoint calculus, universal algebra, category theory, and allegory theory.This textbook-like tutorial presents, besides an introduction, eight coherently written chapters by leading authorities on ordered sets and complete lattices, algebras and coalgebras, Galois connections and fixed point calculus, calculating functional programs, algebra of program termination, exercises in coalgebraic specification, algebraic methods for optimization problems, and temporal algebra.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -A quick description of the conjecture The Baum-Connes conjecture is part of Alain Connes'tantalizing 'noncommuta tive geometry' programme [18]. It is in some sense the most 'commutative' part of this programme, since it bridges with classical geometry and topology. Let r be a countable group. The Baum-Connes conjecture identifies two objects associated with r, one analytical and one geometrical/topological. The right-hand side of the conjecture, or analytical side, involves the K theory of the reduced C\*-algebra c;r, which is the C\*-algebra generated by r in 2 its left regular representation on the Hilbert space C(r). The K-theory used here, Ki(C;r) for i = 0, 1, is the usual topological K-theory for Banach algebras, as described e.g. in [85]. The left-hand side of the conjecture, or geometrical/topological side RKf(Er) (i=O,I), is the r-equivariant K-homology with r-compact supports of the classifying space Er for proper actions of r. If r is torsion-free, this is the same as the K-homology (with compact supports) of the classifying space Br (or K(r,l) Eilenberg-Mac Lane space). This can be defined purely homotopically. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume is a self-contained introduction to interactive proof in high- order logic (HOL), using the proof assistant Isabelle 2002. Compared with existing Isabelle documentation, it provides a direct route into higher-order logic, which most people prefer these days. It bypasses rst-order logic and minimizes discussion of meta-theory. It is written for potential users rather than for our colleagues in the research world. Another departure from previous documentation is that we describe Markus Wenzel¿s proof script notation instead of ML tactic scripts. The l- ter make it easier to introduce new tactics on the y, but hardly anybody does that. Wenzel¿s dedicated syntax is elegant, replacing for example eight simpli cation tactics with a single method, namely simp, with associated - tions. The book has three parts. ¿ The rst part, Elementary Techniques, shows how to model functional programs in higher-order logic. Early examples involve lists and the natural numbers. Most proofs are two steps long, consisting of induction on a chosen variable followed by the auto tactic. But even this elementary part covers such advanced topics as nested and mutual recursion. ¿ The second part, Logic and Sets, presents a collection of lower-level tactics that you can use to apply rules selectively. It also describes I- belle/HOL¿s treatment of sets, functions, and relations and explains how to de ne sets inductively. One of the examples concerns the theory of model checking, and another is drawn from a classic textbook on formal languages.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Buch. Condizione: Neu. Neuware -Modern cryptography depends heavily on number theory, with primality test ing, factoring, discrete logarithms (indices), and elliptic curves being perhaps the most prominent subject areas. Since my own graduate study had empha sized probability theory, statistics, and real analysis, when I started work ing in cryptography around 1970, I found myself swimming in an unknown, murky sea. I thus know from personal experience how inaccessible number theory can be to the uninitiated. Thank you for your efforts to case the transition for a new generation of cryptographers. Thank you also for helping Ralph Merkle receive the credit he deserves. Diffie, Rivest, Shamir, Adleman and I had the good luck to get expedited review of our papers, so that they appeared before Merkle's seminal contribu tion. Your noting his early submission date and referring to what has come to be called 'Diffie-Hellman key exchange' as it should, 'Diffie-Hellman-Merkle key exchange', is greatly appreciated. It has been gratifying to see how cryptography and number theory have helped each other over the last twenty-five years. :'-Jumber theory has been the source of numerous clever ideas for implementing cryptographic systems and protocols while cryptography has been helpful in getting funding for this area which has sometimes been called 'the queen of mathematics' because of its seeming lack of real world applications.

Buch. Condizione: Neu. Neuware - Books on time series models deal mainly with models based on Box-Jenkins methodology which is generally represented by autoregressive integrated moving average models or some nonlinear extensions of these models, such as generalized autoregressive conditional heteroscedasticity models. Statistical inference for these models is well developed and commonly used in practical applications, due also to statistical packages containing time series analysis parts. The present book is based on regression models used for time series. These models are used not only for modeling mean values of observed time se ries, but also for modeling their covariance functions which are often given parametrically. Thus for a given finite length observation of a time series we can write the regression model in which the mean value vectors depend on regression parameters and the covariance matrices of the observation depend on variance-covariance parameters. Both these dependences can be linear or nonlinear. The aim of this book is to give an unified approach to the solution of statistical problems for such time series models, and mainly to problems of the estimation of unknown parameters of models and to problems of the prediction of time series modeled by regression models.

Taschenbuch. Condizione: Neu. Neuware -This book investigates bargaining between two agents. Its objective is to present, to extend, and to apply the present state of theoretical knowledge. A wide range of questions will be considered: First of all, will two parties reach efficient agreements Traditional economic theory gives a generally affirma tive answer for perfectly rational agents, who can carry out complex calcu lations instantaneously and without cost. The book uses innovative methods to analyse the implications of less demanding assumptions. A practical ques tion related to bargaining is: How much power does the design of institutions such as the U. N. Security Council give to each of its members Formally, non permanent members' votes are necessary to pass resolutions, but theoretical investigation of pre-voting negotiation attributes all power to the five perma nent members. Or one may ask whether a society should rather finance the education in higher mathematics for a talented person than remedial training for a retarded person Different concepts of justice yield different answers. Which particular concept is implemented in a given society is also a matter of bargaining, and it is of special philosophical interest to investigate which bargain will be struck in an ideal society in which individual talents and resources are not yet known. Very generally, a bilateral bargaining situation is characterized by two agents - individuals, firms, governments, etc.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condizione: Neu. Neuware -Stochastic portfolio theory is a mathematical methodology for constructing stock portfolios and for analyzing the effects induced on the behavior of these portfolios by changes in the distribution of capital in the market.Stochastic portfolio theory has both theoretical and practical applications: as a theoretical tool it can be used to construct examples of theoretical portfolios with specified characteristics and to determine the distributional component of portfolio return. On a practical level, stochastic portfolio theory has been the basis for strategies used for over a decade by the institutional equity manager INTECH, where the author has served as chief investment officer.This book is an introduction to stochastic portfolio theory for investment professionals and for students of mathematical finance. Each chapter includes a number of problems of varying levels of difficulty and a brief summary of the principal results of the chapter, without proofs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Buch. Condizione: Neu. Neuware -The strong productivity growth of the US and Scandinavian countries in Europe in the 1990s has raised the question whether the ICT sector - information and com munication technology (that is computers plus telecommunications plus digital services)-is the new driving engine of high growth in leading OECD countries. Judging by the empirical evidence for the US, including a new study by McKinsey which gives mixed evidence, it is still too early to clearly dismiss Robert G. Gordon's hypothesis that the acceleration of US output growth is (dis regarding quality problems of price measurement) exclusively due to cyclical factors and increased productivity growth in the computer sector. The counter hypothesis is associated with research by Stiroh and others who argue that there are positive productivity spillover effects from ICT to other sectors. Indeed, it is not clear ex ante whether mainly the Old Economy or the so-called New Economy stands to benefit most from high innovation rates and strong productivity shifts associated with the spreading of digital services. Interestingly, the increased eco nomic role of the internet also contributes to the internationalization of the econ omy since more services have become tradable, and growing import competition itself could stimulate productivity growth and thus contribute to higher growth. If ICT plays a key role in the new economy, there are important implications in the differential degree to which Germany and the US have implemented ICT.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 368 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -CITIES: CHALLENGES AND OPPORTUNITIES FOR SUSTAINABILITY BRANTLEY LIDDLE AND FRED MOAVENZADEH OR at least 4000 years, cities have been centers of cultural, social, technological Fand economic innovation, inventions and their application, and political power. Only in the last 200 years, the industrial era, have urban areas grown so rapidly, and their populations increased so dramatically that their impacts on the natural environ ment are being felt beyond their immediate geographic surroundings. As the 21' cen tury dawns, megacities-great and far-reaching concentrations of power and influ ence-have become centers of the phenomena of globalization and information ex change. These concentrations of people and activity are placing stress on the natural environment so great that it is beginning to have extensive regional, and even global impacts. However, asconcentrations ofpower-political, economic, andintellectual these great urban centers share with the ancestral cities of past millennia the resources to consciously shape the future. The management of these megacities (those having populations of over eight million) in their current formative stages so taxing to natural systems,paradoxicallypresents theopportunity torestoresustainableregional and global environments. Environmental problems consequent to urban growth have two sources: pov erty and affluence. These two conditions often coexist in dramatic contrast within the same city, particularly in developing countries. In terms of environmental impact, poverty-based problems tend to have local effects, while affluence-based problems usually have transboundary and/or global effects.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -'Structural geology is a core component of knowledge needed for intelligent living with our planet, truly sustainable development.' It gives me great pleasure to write this brief foreword for the work by Antonio of Lisboa. When we consider the foundations of our life support systems, cli Ribeiro mate, the biosphere, soil, materials, energy, waste management and today in the word of cities, structural stability, we require exact knowledge of the structure of our planet and change in these structures. Homo sapiens has lived on our planet for a very short period. Our planet is cooling by conduction and convection and it is the structures that result from these processes that control the global climate, our resource base and even soil quality and food secu rity, etc, etc. As the title of this book suggests, some processes are slow and some fast. I was born on a farm in Southern New Zealand, quite close to the magnificent had a profound influen Southern Alps.

Buch. Condizione: Neu. Neuware -Deregulation, privatization and internationalization of the telecommunications industry has brought about enormous changes within both the European and world economy. The dynamics of the Internet and the recent wave of innovations in the telecommunications and computer industry have given rise to new opportunities for entrepreneurship, employment and growth. No doubt, the dynamics and imperfections of today`s information markets raise crucial challenges for Western Europe. The changing patterns of innovation in the digital economy have forced governments to consider new strategies to promote innovation, network effects and growth. In response to these developments this text presents new approaches to macroeconomic modelling, growth theory and trade analysis. Still further, the deregulation policies of OECD-countries are analyzed. An indispensible text for academics and professionals who want to deepen their knowledge of how the New Economy revolution continues to change the economy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book arose out of a paper that I wrote for the World Bank at the request of Ariel Dinar, the editor for the series in which this volume appears. I began that paper by pointing to the growing importance of demand-side considerations in water resources: 'The provision of potable water is one of government's oldest functions with evidence of this activity stretching back thousands of years. During much of that time, water demands were taken as exogenously given and the principle task of authorities was defined as an engineering one: how to supply a given quantity of water at least cost. In recent years, however, concerns have arisen from observations of excessive water use, degraded water quality and continued inadequate service for many, especially the very poor. As a result of these and other concerns, there is a growing effort to view water resource allocation from a perspective that incorporates consumers' preferences along with supply constraints into management plans. ' (Renzetti, 2000, p. 123). The purpose of this volume is to examine, in greater detail than was possible in that article, what is known regarding the economic characteristics of the demand for water. Thus, this book is meant to be an extended critical review of the state of the art.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.
