Artinian Modules over Group Rings / Edition 1

by Leonid Kurdachenko, Javier Otal, Igor Ya Subbotin

Overview

This book highlights important developments on artinian modules over group rings of generalized nilpotent groups. Along with traditional topics such as direct decompositions of artinian modules, criteria of complementability for some important modules, and criteria of semisimplicity of artinian modules, it also focuses on recent advanced results on these matters.

Editorial Reviews

From the reviews:

“The theory of modules over group rings RG for infinite groups G over arbitrary rings R is a very extensive and complex field of research with a great number of scattered results. … Since many of the results appear for the first time in a book it can be recommended warmly to any expert in this field, but also for graduate students who are presented the beauty of the interplay of the theories of groups, rings and representations.” (G. Kowol, Monatshefte für Mathematik, Vol. 152 (4), December, 2007)
