内容摘要:Brauer pairs, introduced by J. Alperin and M. Broué, are essential local data of blocks.Fusion systems is a method to organize these local data of blocks.Nilpotent blocks, defined by M. Broué and L. Puig, can be characterized by fusion systems.Stable equivalences of Morita type, defined also by M. Broué, is a useful tool in the study of blocks of finite groups.L. Puig proved that stable equivalences of Morita type with endopermutation sources between blocks induce isomorphisms of fusion systems.In this talk, we share an observation that stable equivalences of Morita type between blocks (not necessarily with endopermutation sources) induce isomorphisms of some quotient fusion systems.
