Homological theory of representations/ Henning Krause

By: Series: Cambridge Studies in Advanced Mathemnatics | Cambridge Studies in Advanced Mathematics ; 195Publication details: UK: CUP, 2021Description: xxxiv, 482 pages; 24 cmISBN:
  • 9781108838894
Subject(s): DDC classification:
  • 23rd 514.24 K91
Contents:
Part I: Abelian and decived categories -- part II: Orthogonal decompositions -- Part III: Derived equivalences -- Part IV: Purity
Summary: This book is devoted to representations of associative algebras and their homological theory. There are two basic approaches. The passage from representations to chain complexes of representations leads to the study of derived categories. The other approach identifies representations with appropriate functors; this leads to the study of functor categories. We offer an introduction to both approaches and present results which illustrate their beauty and importance.
