摘要
本文讨论Hopf代数对代数的余作用,以强分次环为模型推广了Doi的有关cleft余模代数的结论,得出smash积#(A, B)的一些性质,并定义了余模代数的Jacobson根。
The group-graded rings are instances of Hopf algebra A acting on algebra B. The present paper covers such coaction and expanded Dio' s result about cleft comodule algebra. The smash product # (A,B) is studied farther, and the Jacobson radical of comodule algebra is defined.
