In this paper we introduce and investigate top (bi)comodules of corings, that can be considered as dual to top (bi)modules of rings. The fully coprime spectra of such (bi)comodule...

A frame homomorphism h : A - B is skeletal if x = 1 in A implies that h(x) = 1 in B. It is shown that, in KRegS, the category of compact regular frames with skeletal maps, the subc...

In this paper, it is shown that any non-M-cosingular -supplemented module M is (D3) if and only if M has the summand intersection property. Let N [M ] be any module such that Z M(...
