| 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. |
