摘要
设π为一个群,讨论了弱Doi-Hopfπ-模的半单性或可约性.设(H,A,C)是一个弱Doi-Hopfπ-数据,利用忘却函子将Doi-Hopfπ-模范畴π-CUA中的对象映为右A-模范畴MA中对象,通过对MA中可分单同态进行变形,建立了Doi-Hopfπ-数据积分概念.借助此积分,证明了弱Doi-Hopfπ-模的Mas-chke型定理,推广了一些文献的结果.
Abstract: Let π be a group. We shall discuss the reducibility or semisimpleness of weak Doi-Hopf or-modules. Given a weak Doi- Hopf or-datum (H,A, C), we shall apply the forgetful functor sending the objects in the category π-CuA of weak Doi-Hopf π-modules in- to the category MA of right A-modules, and look for a deformation of a splitting map of a monomorphism in the category MA so that lead to the integral for weak Doi-Hopf or-datum (H,A, C). With the help of the integral introduced, we prove the Maschke-type theorem for weak Doi-Hopf π-modules, which generalizes the results of some literatures.
