Lectures on Block Theory

by Burkhard Külshammer

Overview

In this volume Burkhard Kúlshammer starts with the classical structure theory of finite dimensional algebras, and leads up to Puig's main result on the structure of the so-called nilpotent blocks, which he discusses in the final chapter. All the proofs in the text are given clearly and in full detail, and suggestions for further reading are also included.

Editorial Reviews

"The clearly-written and well-presented text can be used for a one-semester course or a seminar on the subject. I should like to recommend this book to anyone who wishes to learn more about these fascinating new ideas and developments in the representation theory of finite groups." M. Geck, LMS
