About this textbook

This volume introduces some basic theories on computational neuroscience. Chapter 1 is a brief introduction to neurons, tailored to the subsequent chapters. Chapter 2 is a self-contained introduction to dynamical systems and bifurcation theory, oriented towards neuronal dynamics. The theory is illustrated with a model of Parkinson's disease. Chapter 3 reviews the theory of coupled neural oscillators observed throughout the nervous systems at all levels; it describes how oscillations arise, what pattern they take, and how they depend on excitory or inhibitory synaptic connections. Chapter 4 specializes to one particular neuronal system, namely, the auditory system. It includes a self-contained introduction, from the anatomy and physiology of the inner ear to the neuronal network that connects the hair cells to the cortex, and describes various models of subsystems.

An Introduction to Number Theory

Series: Graduate Texts in Mathematics, Preliminary entry 331

2005, Approx. 270 p. 20 illus., Hardcover
ISBN: 1-85233-917-9

About this textbook

The book aims to take readers to a deeper understanding of the patterns of thought that have shaped the modern understanding of number theory. It begins with the fundamental theorem of arithmetic and shows how it echoes through much of number theory over the last two hundred years.

One of the main strengths of this book is the narrative. Everest and Ward present number theory as a living subject, showing how various new developments have drawn upon older traditions.

The authors concentrate on the underlying ideas instead of working out the most general and complete version of a result. They select material from both the algebraic and analytic disciplines and sometimes present several different proofs of a single result to show the differing viewpoints and also to capture the imagination of the reader and help them to discover their own tastes. They also cover important topics of significant interest, eg. elliptic functions and the new primality test, which are often omitted from other books at this level.

Techniques in Variational Analysis

Series: CMS Books in Mathematics,
2005, Approx. 390 p. 14 illus., Hardcover
ISBN: 0-387-24298-8

About this textbook

This book aims to provide a concise account of the essential tools of infinite-dimensional first-order variational analysis that are presently scattered throughout the literature. It also illustrates applications in many parts of analysis, optimization and approximation, control theory, dynamic systems, mathematical economics, and elsewhere.

It is arranged in 3 parts: Part I discusses the fundamentals of variational analysis, and Parts II and II deal with applications. Part II focuses on traditional topics while Part Iii contains problems of a more applied nature. More technical examples and extensions are found at the end of each section. This book is intended for researchers and graduate students who might benefit from using the variational methods. A prerequisite is a working knowledge of basic analysis and principles of functional analysis.

Table of contents

* Introduction * Variational Principles * Variational Techniques in Subdifferential Theory * Variational Techniques in Convex Analysis * Variational Techniques and Multifunctions * Variational Principles in Nonlinear Functional Analysis * Variational Techniques in the Presence of Symmetry

Essential Topology

Series: Springer Undergraduate Mathematics Series,
2005, Approx. 200 p. 50 illus., Softcover
ISBN: 1-85233-782-6

About this textbook

"Essential Topology" brings the most exciting ? and useful - aspects of modern topology within reach of the average second-year undergraduate student. It contains all the essentials. The first chapter provides a complete account of continuity beginning at a level that a high school student could understand. The algebraic notions are introduced slowly through the text, leading the reader to the celebrated Hairy Ball theorem, and on to homotopy and homology ? the cornerstones of contemporary algebraic topology.

Each topic is introduced with a thorough explanation of why it is being studied, and the focus throughout is on providing interesting examples that will motivate the student. Emphasis is placed on the basic objects that occur in research topology, and in its applications to other areas of mathematics.

This book is designed to provide a "one-stop shop" for undergraduate topology, providing enough material for two semester-long courses, and leaving students motivated and prepared for postgraduate study.

Table of contents

Statistical Demography and Forecasting

Series: Springer Series in Statistics,
2005, Approx. 360 p., Hardcover
ISBN: 0-387-23530-2

About this book

Sustainability of pension systems, intergeneration fiscal equity under population aging, and accounting for health care benefits for future retirees are examples of problems that cannot be solved without understanding the nature of population forecasts and their uncertainty. Similarly, the accuracy of population estimates directly affects both the distributions of formula-based government allocations to sub-national units and the apportionment of political representation. The book develops the statistical foundation for addressing such issues. Areas covered include classical mathematical demography, event history methods, multi-state methods, stochastic population forecasting, sampling and census coverage, and decision theory. The methods are illustrated with empirical applications from Europe and the U.S.

For statisticians the book provides a unique introduction to demographic problems in a familiar language. For demographers, actuaries, epidemiologists, and professionals in related fields, the book presents a unified statistical outlook on both classical methods of demography and recent developments. To facilitate its classroom use, exercises are included. Over half of the book is readily accessible to undergraduates, but more maturity may be required to benefit fully from the complete text. Knowledge of differential and integral calculus, matrix algebra, basic probability theory, and regression analysis is assumed.

Juha M. Alho is Professor of Statistics, University of Joensuu, Finland, and Bruce D. Spencer is Professor of Statistics and Faculty Fellow at the Institute for Policy Research, Northwestern University. Both have contributed extensively to statistical demography and served in advisory roles and as statistical consultants in the field.

Table of contents

Combinatorics of Coxeter Groups

Series: Graduate Texts in Mathematics, Vol. 231
2005, Approx. 367 pp., Hardcover
ISBN: 3-540-44238-3

About this textbook

This book is a carefully written exposition of Coxeter groups, an area of mathematics which appears in algebra, geometry, and combinatorics. In this book, the combinatorics of Coxeter groups has mainly to do with reduced expressions, partial order of group elements, enumeration, associated graphs and combinatorial cell complexes, and connections with combinatorial representation theory. While Coxeter groups have already been exposited from algebraic and geometric perspectives, this book will be presenting the combinatorial aspects of Coxeter groups. The authors have included an exposition of Coxeter groups along with a rich variety of exercises, ranging from easy to very difficult, giving the book the unique character of serving as both a textbook and a monograph.
