I* 0-Modules

Abstract

We study rings over which every module is an I*0 -module dual to I 0-module. We describe semiregular rings over which every module is at the same time I*0 -module and I 0-module. We give a description of rings over which every module is a direct sum of injective module and SV -module. We investigate relations between weakly Baer modules and I*0 -modules. © 2014 Allerton Press, Inc.
