Rezumat

In this paper, we define 2-absorbing primary subsemimodules of a semi- module M over a commutative semiring S with 1 6= 0 which is a generalization of primary subsemimodules of semimodules. A proper subsemimodule N of a semimod- ule M is said to be a 2-absorbing primary subsemimodule of M if abm ∈ N implies ab ∈ p(N : M) or am ∈ N or bm ∈ N for some a, b ∈ S and m ∈ M. It is proved that if K is a subtractive subsemimodule of M and p(K : M) is a subtrac- tive ideal of S, then K is a 2-absorbing primary subsemimodule of M if and only if whenever IJN ⊆ K for some ideals I, J of S and a subsemimodule N of M, then IJ ⊆ p(K : M) or IN ⊆ K or JN ⊆ K. In this paper, we prove a number of results concerning 2-absorbing primary subsemimodules.
