Auslander Buchweitz Approximations of Equivariant Modules
Mitsuyasu Hashimoto, "Auslander-Buchweitz Approximations of Equivariant Modules"
Cambridge University Press | 2001 | ISBN: 0521796962 | 296 pages | PDF | 7,2 MB
This book presents a new homological approximation theory in the category of equivariant modules, unifying the Cohen-Macaulay approximations in commutative ring theory and Ringel's theory of Delta-good approximations for quasi-hereditary algebras and reductive groups. The book provides a detailed introduction to homological algebra, commutative ring theory and homological theory of comodules of coalgebras over an arbitrary base. It aims to overcome the difficulty of generalizing known homological results in representation theory.
