拟霍普夫代数的Morita context和Galois扩张

A Morita context and Galois extensions for Quasi-Hopf algebras

Adriana Balan

摘要:

设H是有限维拟霍普夫代数,A是左H-模代数,证明了存在连接smash积A#H和不变量子代数A^{H}的Morita context.我们还定义了伽罗瓦扩展和证明与此森田上下文的连接,在霍普夫的情况下。

英文摘要:

If H is a finite dimensional quasi-Hopf algebra and A is a left H-module algebra, we prove that there is a Morita context connecting the smash product A#H and the subalgebra of invariants A^{H}. We define also Galois extensions and prove the connection with this Morita context, as in the Hopf case.
