Abstract
Let M be an R-module and N ∈ σ[M]. A projective module P with a superfluous epimorphism π:P → N is called projective cover of N in σ[M]. Even if there are enough projective module in σ[M], a module need not have a projective cover. To get projective cover, we need a supplement which does not always exist. In this paper, we will investigate the relation between supplement of a module M and existence projective cover of a factor module of M.
