The composition of dualities in a nondegenerate Morita context

AI Kashu - Journal of Pure and Applied Algebra, 1998 - Elsevier
The relations between the lattices of submodules of members of an Morita context are
studied. The pairs of reversing order maps are defined, which determine the dualities …

Correspondence theorems for nondegenerate modules and their endomorphism rings

ZP Zhou - Proceedings of the American Mathematical Society, 1994 - ams.org
Let $ _RU $ be a left R-module whose Morita context is nondegenerate and $ S={\text
{End}}(U) $. We show the following:(1) There is a projectivity (that is, an order-preserving …

Z Zhengping - Bulletin of the Australian Mathematical Society, 1993 - cambridge.org
The concepts of closed submodule, left and right annihilators are generalised and a
necessary and sufficient condition on any Morita context is given so that the duality and …
