Some Characterized Projective δ-cover

Abstract

In this paper we characterize some properties of projective δ-cover and find some new results with δ-supplemented module M. Let M be a fixed R-module. A δ-cover in M is an δ-small epimorphism from M onto P.Thes concept introduce by Zhou [14]. A δ-cover is projective δ-cover( M-projective δ-cover) in case M is projective.

Keywords: Singular, non singular, simple, small, δ-small, cover, δ-cover, supplement, δ-supplement.
