Duality of Comodules over a Group Coring
摘要
Abstract
Let C be a G-A-coring, and MCfgp (respectively, CfgpM) be the category of right (respectively, left) C-comodules which are finitely generated and projective as right (respectively, left) A-modules. This paper proves that MCfgpand CfgpM are equivalent. Based on this fact, we obtain a pair of adjoint functors between the category of C-comodules and the category of certain modules.关键词
