Levy Processes in Lie Groups

Publication is planned for May 2004 | Hardback | 220 pages | ISBN: 0-521-83653-0

The theory of Levy processes in Lie groups is not merely an extension of the theory of Levy processes in Euclidean spaces. Because of the unique structures possessed by non-commutative Lie groups, these processes exhibit certain interesting limiting properties which are not present for their counterparts in Euclidean spaces. These properties reveal a deep connection between the behaviour of the stochastic processes and the underlying algebraic and geometric structures of the Lie groups themselves. The purpose of this work is to provide an introduction to Levy processes in general Lie groups, the limiting properties of Levy processes in semi-simple Lie groups of non-compact type and the dynamical behavior of such processes as stochastic flows on certain homogeneous spaces. The reader is assumed to be familiar with Lie groups and stochastic analysis, but no prior knowledge of semi-simple Lie groups is required.

Contents

1. Levy processes in Lie groups; 2. Generator and stochastic integral equation of a Levy process; 3. Semi-simple Lie gropus of non-compact type; 4. Limiting propersties of Levy processes; 5. Rate of convergence; 6. Levy processes as stochastic flows.

Equivalence and Duality for Module Categories
with Tilting and Cotilting for Rings

Publication is planned for June 2004 | Hardback | 150 pages | ISBN: 0-521-83821-5

This book provides a unified approach to much of the theories of equivalence and duality between categories of modules that has transpired over the last 45 years. In particular, during the past dozen or so years many authors (including the authors of this book) have investigated relationships between categories of modules over a pair rings that are induced by both covariant and contravariant representable functors, in particular by tilting and cotilting theories. By here collecting and unifying the basic results of these investigations with innovative and easily understandable proofs, the authorsf aim is to provide an aid to further research in this central topic in abstract algebra, and a reference for all whose research lies in this field.

Contents

0. Preface; 1. Some module theoretic observations; 2. Representable equivalences; 3. Tilting modules; 4. Representable dualities; 5. Cotilting; A. Adjoints and category equivalnece; B. Noetherian serial rings.

Duality for Smooth Families in Equivariant Stable Homotopy Theory

Description

In this volume, the author formulates and proves a duality theorem for the equivariant stable homotopy category, using the language of Verdier duality from sheaf theory. He works with the category of $G$-equivariant spectra (for a compact Lie group $G$) parametrized over a $G$-space $X$ and considers a smooth equivariant family $f: X \rightarrow Y$, which is a $G$-equivariant bundle whose fiber is a smooth compact manifold, and with actions of subgroups of $G$ varying smoothly over $Y$. Then the main theorem is a natural equivalence between a certain direct image functor $f_*$ and a "direct image with proper support functor" $f_!$, in the stable equivariant homotopy category over $Y$. In particular, the Wirthmuller and Adams isomorphisms in equivariant stable homotopy theory turn out to be special cases of this duality theorem.

Understanding Calculus, 2nd Edition

ISBN: 0-471-43307-1
Paperback
320 pages
February 2003, Wiley-IEEE Press

Description

Everything you need to know?basic essential concepts?about calculus
For anyone looking for a readable alternative to the usual unwieldy calculus text, herefs a concise, no-nonsense approach to learning calculus. Following up on the highly popular first edition of Understanding Calculus, Professor H. S. Bear offers an expanded, improved edition that will serve the needs of every mathematics and engineering student, or provide an easy-to-use refresher text for engineers.

Understanding Calculus, Second Edition provides in a condensed format all the material covered in the standard two-year calculus course. In addition to the first editionfs comprehensive treatment of one-variable calculus, it covers vectors, lines, and planes in space; partial derivatives; line integrals; Greenfs theorem; and much more. More importantly, it teaches the material in a unique, easy-to-read style that makes calculus fun to learn. By explaining calculus concepts through simple geometric and physical examples rather than formal proofs, Understanding Calculus, Second Edition, makes it easy for anyone to master the essentials of calculus.

If the dry "theorem-and-proof" approach just doesnft work, and the traditional twenty pound calculus textbook is just too much, this book is for you.
