Brauer pairs, pointed groups, and block fusion
Matthew Gelvin
Bilkent University, Turkey
Özet : In this talk we will describe how a block B of the finite group G gives rise to a fusion system on the block's defect group D. The rough idea is that G induces conjugacy relations among the subgroups of D, but we only consider those conjugations that respect B. To make sense of what this means, we introduce the notion of a Brauer pair, whose technical properties we will prove by considering the more refined notion of a local pointed group.
