Morita contexts and closure operators in modules

Authors: Caşu Alexei


The relations between the classes of closure operators of two module categories $R$-Mod and $S$-Mod are studied in the case when an arbitrary Morita context $\,(R,\, _{\ind R}\,U_{\ind S},\, _{\ind S}V_{\ind R},S)$ is given. By the functors $Hom_{\ind R}(U,\mbox{-})\,$ and $Hom_{\ind S}(V,\mbox{-})\,$ two mappings are defined between the closure operators of these categories. Basic properties of these mappings are investigated.
