On the separability of the restriction functor
Let \(G\) be a group, \(\Lambda=\bigoplus_{\sigma \in G}\Lambda_{\sigma}\) a strongly graded ring by \(G\), \(H\) a subgroup of \(G\) and \(\Lambda_{H}=\bigoplus_{\sigma \in H}\Lambda_{\sigma}\). We give a necessary and sufficient condition for the ring \(\Lambda/\Lambda_{H}\) to be separable, gener...
