Singular Perturbation Theory
Mathematical and Analytical Techniques with Applications to Engineering

2005, XIV, 308 p., Hardcover
ISBN: 0-387-23200-1

About this book

The theory of singular perturbations has evolved as a response to the need to find approximate solutions (in an analytical form) to complex problems. Typically, such problems are expressed in terms of differential equations which contain at least one small parameter, and they can arise in many fields: fluid mechanics, particle physics, and combustion processes, to name but three.

Progress in Galois Theory

Series: Developments in Mathematics, Vol. 12
2005, X, 168 p., Hardcover
ISBN: 0-387-23533-7

About this book

The theme of this book are the interactions between group theory and algebra/geometry/number theory, showing ubiquity and power of the basic principle of Galois theory. The book presents recent developments in a major line of work about covers of the projective line (and other curves), their fields of definition and parameter spaces, and associated questions about arithmetic fundamental groups. This is intimately tied up with the Inverse Problem of Galois Theory, and uses methods of algebraic geometry, group theory and number theory.

Table of contents

Preface.- Supplementary Thoughts on Symplectic Groups.- Automorphisms of the Modular Curve.- Reducing the Fontaine-Mazur Conjecture to Group Theory.- Relating Two Genus 0 Problems of John Thompson.- Relatively Projective Groups as Absolute Galois Groups.- Invariants of Binary Forms.- Some Classical Views on the Parameters of GT.- The Image of a Hurwitz Space under the Moduli Map.- Very Simply Presentation: Variations on a Theme of Clifford.

About this textbook

From the reviews of the First Edition:

"This excellent book is based on several sets of lecture notes written over a decade and has its origin in a one-semester course given by the author at the ETH, Zurich, in the spring of 1970. The author's aim was to present some of the best features of Markov processes and, in particular, of Brownian motion with a minimum of prerequisites and technicalities. The reader who becomes acquainted with the volume cannot but agree with the reviewer that the author was very successful in accomplishing this goalcThe volume is very useful for people who wish to learn Markov processes but it seems to the reviewer that it is also of great interest to specialists in this area who could derive much stimulus from it. One can be convinced that it will receive wide circulation." (Mathematical Reviews)

This new edition contains 9 new chapters which include new exercises, references, and multiple corrections throughout the original text.

Table of contents

Preface.- Part I: Markov Process. Basic Properties. Hunt Process. Brownian Motion. Potential Developments. Bibliography.- Part II: Generalities. Markov Chains: A Fireside Chat. Ray Processes. Application to Markov Chains. Time Reversal. h-Transforms. Death and Transfiguration: A Fireside Chat. Processes in Duality. The Basis of Duality: A Fireside Chat. References. Index.

Hamiltonian Dynamics - Theory and Applications
Lectures given at the C.I.M.E. Summer School held in Cetraro, Italy, July 1-10, 1999

Series: Lecture Notes in Mathematics, Vol. 1861
2005, XIV, 177 p., Softcover
ISBN: 3-540-24064-0

About this book

This volume compiles three series of lectures on applications of the theory of Hamiltonian systems, contributed by some of the specialists in the field. The aim is to describe the state of the art for some interesting problems, such as the Hamiltonian theory for infinite-dimensional Hamiltonian systems, including KAM theory, the recent extensions of the theory of adiabatic invariants, and the phenomena related to stability over exponentially long times of Nekhoroshev's theory. The books may serve as an excellent basis for young researchers, who will find here a complete and accurate exposition of recent original results and many hints for further investigation.

A. Giorgilli: Preface.- G. Benettin: Physical Applications of Nekhoroshev Theorem and Exponential Estimates.- J. Henrard: The Adiabatic Invariant Theory and Applications.- S. Kuksin: Lectures on Hamiltonian Methods in Nonlinear PDEs.

Convex Polyhedra

Series: Springer Monographs in Mathematics,
2005, XII, 539 p. 165 illus., Hardcover
ISBN: 3-540-23158-7

About this book

Convex Polyhedra is one of the classics in geometry. There simply is no other book with so many of the aspects of the theory of 3-dimensional convex polyhedra in a comparable way, and in anywhere near its detail and completeness. It is the definitive source of the classical field of convex polyhedra and contains the available answers to the question of the data uniquely determining a convex polyhedron. This question concerns all data pertinent to a polyhedron, e.g. the lengths of edges, areas of faces, etc. This vital and clearly written book includes the basics of convex polyhedra and collects the most general existence theorems for convex polyhedra that are proved by a new and unified method. It is a wonderful source of ideas for students.

The English edition includes numerous comments as well as added material and a comprehensive bibliography by V.A. Zalgaller to bring the work up to date. Moreover, related papers by L.A.Shor and Yu.A.Volkov have been added as supplements to this book.
