\u201cMackey Category of Brauer Pairs\u201d<\/p>\n
Abstract: For a finite group G, and an algebraically closed field of char p, G acts on kG by conjugation, making it a G-algebra. A pair (P,c) such that P is a p-subgroup of G and c is a block idempotent of kC_G(P) is called a Brauer pair. Brauer pairs form a refinement of the G-poset of p-subgroups of a finite group. In this talk, we will define the ordinary Macket biset category mathcal{C} of Brauer pairs (shortly, Mackey category of Brauer pairs) and if time permits, show that the category algebra of mathcal{C} is semisimple.<\/p>\n
