REPRESENTATIONS OF FINITE AND LIE GROUPS

This book provides an introduction to representations of both finite and compact groups. The proofs of the basic results are given for the finite case, but are so phrased as to hold without change for compact topological groups with an invariant integral replacing the sum over the group elements as an averaging tool. Among the topics covered are the relation between representations and characters, the construction of irreducible representations, induced representations and Frobenius reciprocity. Special emphasis is given to exterior powers, with the symmetric group Sn as an illustrative example. The book concludes with a chapter comparing the representations of the finite group SL2(p) and the non-compact Lie group SL2(?).

Contents:

Resolution of Curve and Surface Singularities in Characteristic Zero

About this book

This book covers the beautiful theory of resolutions of surface singularities in characteristic zero. The primary goal is to present in detail, and for the first time in one volume, two proofs for the existence of such resolutions. One construction was introduced by H.W.E. Jung, and another is due to O. Zariski. Jung's approach uses quasi-ordinary singularities and an explicit study of specific surfaces in affine three-space. In particular, a new proof of the Jung-Abhyankar theorem is given via ramification theory. Zariski's method, as presented, involves repeated normalisation and blowing up points. It also uses the uniformization of zero-dimensional valuations of function fields in two variables, for which a complete proof is given. Despite the intention to serve graduate students and researchers of Commutative Algebra and Algebraic Geometry, a basic knowledge on these topics is necessary only. This is obtained by a thorough introduction of the needed algebraic tools in the two appendices.

About this book

This book offers a modern updated review on the most important activities in today dynamical systems and statisitical mechanics by some of the best experts in the domain. It gives a contemporary and pedagogical view on theories of classical and quantum chaos and complexity in hamiltonian and ergodic systems and their applications to anomalous transport in fluids, plasmas, oceans and atom-optic devices and to control of chaotic transport. The book is issued from lecture notes of the International Summer School on "Chaotic Dynamics and Transport in Classical and Quantum Systems" held in Cargese (Corsica) 18th to the 30th August 2003. It reflects the spirit of the School to provide lectures at the post-doctoral level on basic concepts and tools. The first part concerns ergodicity and mixing, complexity and entropy functions, SRB measures, fractal dimensions and bifurcations in hamiltonian systems. Then, models of dynamical evolutions of transport processes in classical and quantum systems have been largly explained. The second part concerns transport in fluids, plasmas and reacting media. On the other hand, new experiments of cold optically trapped atoms and electrodynamics cavity have been thoroughly presented. Finally, several papers bears on synchronism and control of chaos. The target audience of the proceedings are physicists , mathematicians and all scientists involved in Chaos and Dynamical Systems Theory and their fondamental applications in Physics and in the Science of Complex and Nonlinear phenomena.

The book includes historical and biographical information, a wide range of problem types, selected readings on a variety of topics, and many references for additional study. Since all these materials are collected into a single book, teachers and students can easily choose items most suitable for their purpose. Teachers may use the book as a supplement to their courses, while students may read much of the book on their own. No other book has been written specifically as a supplement for a real analysis course.

Contents

Reviews

eThe book offers even more than its title suggests: a true trove of resources for students (and their teachers) who face the exciting - but often rough - passage from the routine calculations of elementary calculus to the deeper arguments and insights of real analysis. There are gems here for average students who need review; for the quickest students who need mathematical challenges; for teachers who need ideas; and for everyone with a taste for mathematical highlights and culture.f Paul Zorn, St Olaf College

eBrabenec has provided a rich smorgasbord of mathematical analysis - including a host of problems, historical essays, and selected readings-from which no one should go away hungry.f William Dunham, Muhlenberg College

Global Optimization Using Interval Analysis,
Second Edition, Revised and Expanded

Print ISBN: 0-8247-4059-9

Series Volume: 264
This item is part of the Pure and Applied Mathematics series.

Description

This Second Edition contains an up-to-date discussion of interval methods for solving systems of nonlinear equations and global optimization problems. The latter can be unconstrained or have inequality and/or equality constraints. Provided algorithms are guaranteed to find and bound all solutions to these problems despite bounded errors in data, in approximations, and from use of rounded arithmetic.

This edition expands and improves various aspects of its forerunner and features significant new discussions, such as those on the use of consistency methods to enhance algorithm performance. It is shown that proof of existence and uniqueness of solutions can be obtained as a simple byproduct of computing a solution.

Employing a closed set-theoretic foundation for interval computations, Global Optimization Using Interval Analysis, Second Edition simplifies algorithm construction and increases generality of interval arithmetic.

Providing methods for solving perturbed systems of nonlinear equations and optimization problems?and including problems containing integers and nondifferentiable functions?this reference/text authoritatively informs nonlinear mathematical analysts, applied mathematicians, operations theorists, hardware and software engineers, programmers, and graduate-level students in these disciplines.
