Quasi-frobenius rings

WebA module M is called quasi principally (or semi) injective, if it is M-principally injective. 1.1. Preliminaries. Throughout this paper, by a ring R we always mean an associative ring with identity and every R-module M is a unitary right R- module. WebIn Pure and Applied Mathematics, 1979. Definition. A ring R is quasi-Frobenius if it is left and right noetherian and R is an injective left R-module.. It can be shown that the asymmetry of the definition is only virtual: R must be injective as a right R-module [Jans, 1964, p. 78].It is …
