A Tour of Representation Theory
Share this pageMartin Lorenz
Representation theory investigates the
different ways in which a given algebraic object—such as a group
or a Lie algebra—can act on a vector space. Besides being a
subject of great intrinsic beauty, the theory enjoys the additional
benefit of having applications in myriad contexts outside pure
mathematics, including quantum field theory and the study of molecules
in chemistry.
Adopting a panoramic viewpoint, this book offers an introduction to
four different flavors of representation theory: representations of
algebras, groups, Lie algebras, and Hopf algebras. A separate part of
the book is devoted to each of these areas and they are all treated in
sufficient depth to enable and hopefully entice the reader to pursue
research in representation theory.
The book is intended as a
textbook for a course on representation theory, which could
immediately follow the standard graduate abstract algebra course, and
for subsequent more advanced reading courses. Therefore, more than 350
exercises at various levels of difficulty are included. The broad
range of topics covered will also make the text a valuable reference
for researchers in algebra and related areas and a source for graduate
and postgraduate students wishing to learn more about representation
theory by self-study.
Readership
Graduate students and researchers interested in various aspects of representation theory.
Reviews & Endorsements
Complemented by more than 350 exercises at various levels of difficulty, this text is a valuable reference for researchers and students in algebra and related fields, and is ideally suitable for learning representation theory by self-study.
-- Dongwen Liu, Mathematical Reviews
This excellent book is one that I wish had been written when I was a student...Had I the benefit of a book like this one in my early graduate years, I could have saved myself a lot of time...This is a very nicely written book, with student motivation always in mind. The level of difficulty increases as the book proceeds (as is only reasonable) but at no point does the book become too difficult for a well-prepared graduate student reader...I like this book a lot, and consider it to be a very valuable addition to the existing textbook literature on representation theory. It would not surprise me if it becomes the market leader in books on graduate-level representation theory.
