“…It is shown in [10,Lemma 2.1] that if N is a graded submodule of M , then (N : R M ) is a graded ideal of R. The annihilator of M is defined as (0 : R M ) and is denoted by Ann R (M ). A proper graded submodule C of M is said to be a completely graded irreducible if C = ∩ α∈∆ C α , where {C α } α∈∆ is a family of graded submodules of M , implies that C = C β for some β ∈ ∆, (see [1]). A non-zero graded submodule N of M is said to be a graded second if for each r ∈ h(R), the endomorphism of N given by multiplication by r is either surjective or zero, (see [7]).…”
