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