Stable equivalences with endopermutation source, slash functors, and functorial equivalences

Abstract: We show that a bimodule of two block algebras of finite groups which has an endopermutation module as a source and which induces a stable equivalence of Morita type gives rise, via slash functors, to a family of bimodules of local block algebras with endopermutation source which induce Morita equivalences. As an application, we show that Morita (resp. stable) equivalences with endopermutation source imply functorial (resp. stable functorial) equivalences defined by Bouc and Y{\i}lmaz.
