Correspondences of coclosed submodules

Abstract

We establish an order-preserving bijective correspondence between the sets of coclosed elements of some bounded lattices related by suitable Galois connections. As an application, we deduce that if MM is a finitely generated quasi-projective left RR-module with S=EndR(M)S=End_R(M) and NN is an MM-generated left RR-module, then there exists an order-preserving bijective correspondence between the sets of coclosed left RR-submodules of NN and coclosed left SS-submodules of HomR(M,N)Hom_R(M,N).
