Representation theory is an important part of modern mathematics, not only as a subject in its own right but also as a tool for many applications. It provides a

Very roughly speaking, representation theory studies symmetry in linear spaces. It is a beautiful mathematical subject which has many applications, ranging from

A short introduction ideal for students learning category theory for the first time.

Introducing the representation theory of groups and finite dimensional algebras, first studying basic non-commutative ring theory, this book covers the necessar

This book is an introduction to the use of triangulated categories in the study of representations of finite-dimensional algebras. In recent years representatio
