On Right Orthogonal Classes and Cohomology Over Ding–Chen Rings

On Right Orthogonal Classes and Cohomology Over Ding–Chen Rings In this paper, we investigate the properties of right orthogonal modules of $${{\mathscr {C}}}$$ C , where $${{\mathscr {C}}}$$ C is a class of left R-modules. As an application, we investigate the properties of right orthogonal modules of Ding injective left R-modules, and present various characterizations of semisimple and von Neumann regular rings and so on. Moreover, we also consider another cohomology, strong Tate cohomology, which connects the usual cohomology with the Ding cohomology. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the Malaysian Mathematical Sciences Society Springer Journals

Abstract

In this paper, we investigate the properties of right orthogonal modules of $${{\mathscr {C}}}$$ C , where $${{\mathscr {C}}}$$ C is a class of left R-modules. As an application, we investigate the properties of right orthogonal modules of Ding injective left R-modules, and present various characterizations of semisimple and von Neumann regular rings and so on. Moreover, we also consider another cohomology, strong Tate cohomology, which connects the usual cohomology with the Ding cohomology.
