Description

Representation Theory of Finite Groups is a five chapter text that covers the standard material of representation theory.

This book starts with an overview of the basic concepts of the subject, including group characters, representation modules, and the rectangular representation. The succeeding chapters describe the features of representation theory of rings with identity and finite groups. These topics are followed by a discussion of some of the application of the theory of characters, along with some classical theorems. The last chapter deals with the construction of irreducible representations of groups.

This book will be of great value to graduate students who wish to acquire some knowledge of representation theory.
