MININJECTIVE RINGS AND QUASI FROBENIUS RINGS

Abstract

A ring R is called right mininjective if every isomorphsim between simple right ideals is given by left multiplication by an element of R. In this paper we consider that the necessary and sufficient condition for that Trivial extension of R by V , i.e. T (R, V ) is mininjective. We also study the split null extension R and S by V .
