MATH Seminar: “Mackey Category of Brauer Pairs,” Utku Okur, SA-141, 10:40AM December 18 (EN)

Dear Colleagues and Students,

You are cordially invited to the Algebra Seminar organized by the Department of Mathematics.

Speaker: Utku Okur (Bilkent)

“Mackey Category of Brauer Pairs”

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.
