Synopses & Reviews
The second of two volumes, Representation Theory and Cohomology, provides an introduction to the representation theory of finite groups and associative algebras. The subject is viewed from the perspective of homological algebra and the theory of representations of finite dimensional algebras. The author emphasizes modular representations and the homological algebra associated with their categories. This volume concentrates on the cohomology of groups, always however, with representation in view. It begins with a background reference chapter, then proceeds to an overview of the algebraic topology and K-theory associated with cohomology of groups, especially the work of Quillen. Later chapters look at algebraic and topological proofs of the finite generation of the cohomology ring of a finite group and an algebraic approach to the Steenrod operations in group cohomology. The book culminates with a chapter on the theory of varieties for modules.
Synopsis
Author D. Benson concentrates on the cohomology of groups, always with representations in view. He also gives an overview of the algebraic topology and K-theory associated with the cohomology of groups and discusses algebraic and topological proofs of the finite generation of the cohomology ring of a finite group. Students and researchers will appreciate this exposition on the essential results of modern representation theory.
Synopsis
The heart of the book is a lengthy introduction to the representation theory of finite dimensional algebras, in which the techniques of quivers with relations and almost split sequences are discussed in some detail.
