On Picard groups of blocks of finite group algebras
Location: MSRI: Simons Auditorium
I will present joint work with Robert Boltje and Markus Linckelmann on the structure of the Picard group of self Morita equivalences of a block of a finite group algebra over a complete discrete valuation ring. In particular, I will give a description of the subgroup of endopermutation source Morita equivalences in terms of the underlying fusion system, Dade group, and source algebra.
