Abstract:letII be a finite dimensional Hopf algebra over a field k, and A an II--module algebra. In the present peper,we apply the Morita context formed in [1] to study connections between A A A # II about their primitivity, subdirect irreductbility, their extended centroids and other important properties. We also discuss the properties of associatied Morita context rings.
Keywords:and Phrases Smash Product  Morita Context  Ring  Extended Centroid  Normal Class
