Modules Over Endomorphism Rings as Homotopy Classes

  • Chapter
Abelian Groups and Modules

Part of the book series: Mathematics and Its Applications ((MAIA,volume 343))

Abstract

Let R be an associative ring with identity, fix a right R-module A, and let E = End R (A) be he ring of R-module endomorphisms of A. View as an E-R-bimodule, and let M T denote the category of right modules over a ring T. To emphasize the arbitrary selection of R, module will mean right R-module and Hom = Hom R throughout this paper.
