CalTitle1: Algebra Seminar: From the general linear group to matroids

Auth: kevinc@120.88.165.116 (kcou7211) in SMS-WASM

Carl Mautner (University of California, Riverside) Friday 1 September, 2:30-3:30pm, Place: Carslaw 375 Title: From the general linear group to matroids Abstract: The Schur algebra is a finite-dimensional algebra that encodes the rich representation theory of the general linear group. Motivated by geometry, Tom Braden and I have defined a similar algebra associated to any graph or, more generally, matroid. After introducing the various objects involved, I will discuss how our work "categorifies" some combinatorial results about matroids and discuss some new combinatorial questions that it raises.
