Rouquier's theorem on representation dimension

Representation Theory 2007-05-23 v2 Algebraic Geometry

Abstract

Based on work of Rouquier, some bounds for Aulander's representation dimension are discussed. More specifically, if X is a reduced projective scheme of dimension n over some field, and T is a tilting complex of coherent O_X-modules, then the representation dimension of the endomorphism algebra of T is at least n.
