Fusions and Clifford extensions (Q1755300)

In this paper, the authors introduced a notion of \(\overline{G}\)-fusion of local pointed groups with respect to a given normal subgroup \(H\) of a finite group \(G\) and a \(G\)-invariant block \(b\) of \(\mathcal{O}H\) and show that certain Clifford extensions associated to these pointed groups are invariant under group graded basic Morita equivalences.
