摘要:

通过引入双边群Smash余积的概念, 给出了双边群Smash余积成为Hopf群余代数的充要条件, 并利用群余代数中积分理论讨论了双边群Smash余积的
半单性.

关键词: Hopf群余代数, 余模余代数, 半单性

Abstract:

By introducing the concept of two\|sided group Smash coproducts, the authors presented the necessary and sufficient conditions for two
sided group Smash coproducts to be Hopf group coalgebras. Using the integral theories of Hopf group coalgebras, we discussed the semisimplicity of twosided group Smash coproducts.

Key words: Hopf group coalgebras, comodule coalgebras, semisimplicity
