Описание: This self-contained book is devoted to the study of the acoustic wave equations and the Maxwell system, the two most common waves equations that are encountered in physics or in engineering. It presents a detailed analysis of their mathematical and physical properties. In particular, the author focuses on the study of the harmonic exterior problems, building a mathematical framework which provides the existence and uniqueness of the solutions. Acoustic and electromagnetic waves underlie a vast range of modern technology from sonar, radio, and television to microwave heating and electromagnetic compatibility analysis. Mathematical modeling of these waves has undergone considerable growth in recent years, and this timely book, written by a leading international researcher, presents the research in a careful and complete way.

Описание: This book primarily focuses on the concept of forgetting, with particular emphasis on how we can trace the forgotten in contemporary life writing and memory texts. It consists of two main parts: the first concentrates on life writing in particular and what the author calls “scenes of forgetting”; the second examines both fiction and autobiographies that deal with questions of collective memory/forgetting. The book’s principal aim is to map methods and strategies writers employ when writing the forgotten – it argues that forgetting is a constant companion in any memory text and plays a decisive role in the memory work performed in the texts. The main theoretical objective is to examine carefully the connection between collective memory and personal memory, by drawing from two disciplines at once: memory studies and theories on life writing. By considering both areas of research, the conclusions of this study are able to feed into both theoretical perspectives.

Описание: The invention of quantum groups is one of the outstanding achievements of mathematical physics and mathematics in the late twentieth century. The birth of the new theory and its rapid development are results of a strong interrelation between mathematics and physics. Quantu groups arose in the work of L.D. Faddeev and the Leningrad school on the inverse scattering method in order to solve integrable models. The algebra Uq(sh) appeared first in 1981 in a paper by P.P. Kulish and N.Yu. Reshetikhin on the study of integrable XYZ models with highest spin. Its Hopf algebra structure was discovered later by E.K. Sklyanin. A major event was the discovery by V.G. Drinfeld and M. Jimbo around 1985 of a class of Hopf algebras which can be considered as one-parameter deforma- tions of universal enveloping algebras of semisimple complex Lie algebras. These Hopf algebras will be called Drinfeld-Jimbo algebras in this book. Al- most simultaneously, S.L. Woronowicz invented the quantum group SUq(2) and developed his theory of compact quantum matrix groups. An algebraic approach to quantized coordinate algebras was given about this time by Yu.I. Manin.

Описание: This book is based on several courses given by the authors since 1966. It introduces the reader to the representation theory of compact Lie groups. We have chosen a geometrical and analytical approach since we feel that this is the easiest way to motivate and establish the theory and to indicate relations to other branches of mathematics. Lie algebras, though mentioned occasionally, are not used in an essential way. The material as well as its presentation are classical; one might say that the foundations were known to Hermann Weyl at least 50 years ago. Prerequisites to the book are standard linear algebra and analysis, including Stokes' theorem for manifolds. The book can be read by German students in their third year, or by first-year graduate students in the United States. Generally speaking the book should be useful for mathematicians with geometric interests and, we hope, for physicists. At the end of each section the reader will find a set of exercises. These vary in character: Some ask the reader to verify statements used in the text, some contain additional information, and some present examples and counter- examples. We advise the reader at least to read through the exercises.
Описание: At the time I learned quantum field theory it was considered a folk theo- rem that it is easy to construct field theories fulfilling either the locality or the spectrum condition. The construction of a theory fulfilling locality without a pos- itive energy representation was first done by Doplicher, Regge, and Singer [DRS].
Описание: This book aims to provide a self-contained exposition of what is known about Z2-graded quantum stochastic calculus and to provide a framework for future research into this fertile area.
