Dynamics of Markets
Econophysics and Finance

Publication is planned for April 2004 | Hardback | 216 pages 22 line diagrams 1 half-tone | ISBN: 0-521-82447-8

Standard texts and research in economics and finance ignore the absence of evidence from the analysis of real, unmassaged market data to support the notion of Adam Smithfs stabilizing Invisible Hand. The neoclassical equilibrium model forms the theoretical basis for the positions of the U.S. Treasury, the World Bank and the European Union, accepting it as their credo. It provides the theoretical underpinning for globalization, expecting to achieve the best of all possible worlds via the deregulation of all markets. In stark contrast, this text introduces a new empirically-based model of financial market dynamics that explains volatility, prices options correctly and clarifies the instability of financial markets. The emphasis is on understanding how real markets behave, not how they hypothetically eshouldf behave. This text is written for physics graduate students and finance specialists, but will also serve as a valuable resource for those with a less mathematical background.

Measure Theory and Filtering
An Introduction with Applications

Publication is planned for April 2004 | Hardback | 337 pages 10 tables 95 exercises | ISBN: 0-521-83803-7

The estimation of noisily observed states from a sequence of data has traditionally incorporated ideas from Hilbert spaces and calculus based probability theory. As conditional expectation is the key concept, the correct setting for filtering theory is that of a probability space. Graduate engineers, mathematicians and those working in quantitative finance wishing to use filtering techniques will find in the first half of this book an accessible introduction to measure theory, stochastic calculus, and stochastic processes, with particular emphasis on martingales and Brownian motion. Exercises are included. The book then provides an excellent usersf guide to filtering: basic theory is followed by a thorough treatment of Kalman filtering, including recent results which extend the Kalman filter to provide parameter estimates. These ideas are then applied to problems arising in finance, genetics and population modelling in three separate chapters, making this a comprehensive resource for both practitioners and researchers.

Contents

Part I. Theory: 1. Basic Probability Concepts; 2. Stochastic Processes; 3. Stochastic Calculus; 4. Change of Measures; Part II. Applications: 5. Kalman Filtering; 6. Financial Applications; 7. A Genetics Model; 8. Hidden Populations.

Linear Operators and Linear Systems
An Analytical Approach to Control Theory

Publication is planned for April 2004 | Hardback | 200 pages 6 line diagrams 101 exercises | ISBN: 0-521-83734-0

Linear systems can be regarded as a causal shift-invariant operator on a Hilbert space of signals, and by doing so this book presents an introduction to the common ground between operator theory and linear systems theory. The book therefore includes material on pure mathematical topics such as Hardy spaces, closed operators, the gap metric, semigroups, shift-invariant subspaces, the commutant lifting theorem and almost-periodic functions, which would be entirely suitable for a course in functional analysis; at the same time, the book includes applications to partial differential equations, to the stability and stabilization of linear systems, to power signal spaces (including some recent material not previously available in books), and to delay systems, treated from an input/output point of view. Suitable for students of analysis, this book also acts as an introduction to a mathematical approach to systems and control for graduate students in departments of applied mathematics or engineering.

Contents

1. Operators and Hardy spaces; 2. Closed Operators; 3. Shift-invariance adn causality; 4, Stabilityand stabilization; 5. spaces of persistent signals; 6. Delay systems.

Quantum Theory as an Emergent Phenomenon

Publication is planned for May 2004 | Hardback | 240 pages 2 figures | ISBN: 0-521-83194-6

Quantum mechanics is our most successful physical theory. However, it raises conceptual issues that have perplexed physicists and philosophers of science for decades. This book develops a new approach, based on the proposal that quantum theory is not a complete, final theory, but is in fact an emergent phenomenon arising from a deeper level of dynamics. The dynamics at this deeper level is taken to be an extension of classical dynamics to non-commuting matrix variables, with cyclic permutation inside a trace used as the basic calculational tool. With plausible assumptions, quantum theory is shown to emerge as the statistical thermodynamics of this underlying theory, with the canonical commutation/anticommutation relations derived from a generalized equipartition theorem. Brownian motion corrections to this thermodynamics are argued to lead to state vector reduction and to the probabilistic interpretation of quantum theory, making contact with recent phenomenological proposals for stochastic modifications to Schrodinger dynamics.

Contents

0. Introduction and overview; 1. Trace dynamics: the classical Lagrangian and Hamiltonian dynamics of matrix models; 2. Additional generic conserved quantities; 3. Trace dynamics models with global supersymmetry; 4. Statistical mechanics of matrix models; 5. The emergence of quantum field dynamics; 6. Brownian motion corrections to Schrodinger dynamics; 7. Discussion and outlook.

An Introduction to Noncommutative Noetherian Rings, 2nd Edition

This introduction to noncommutative noetherian rings is intended to be accessible to anyone with a basic background in abstract algebra. It can be used as a second-year graduate text, or as a self-contained reference. Extensive explanatory discussion is given, and exercises are integrated throughout. Various important settings, such as group algebras, Lie algebras, and quantum groups, are sketched at the outset to describe typical problems and provide motivation. The text then develops and illustrates the standard ingredients of the theory: e.g., skew polynomial rings, rings of fractions, bimodules, Krull dimension, linked prime ideals. Recurring emphasis is placed on prime ideals, which play a central role in applications to representation theory. This edition incorporates substantial revisions, particularly in the first third of the book, where the presentation has been changed to increase accessibility and topicality. New material includes the basic types of quantum groups, which then serve as test cases for the theory developed.
