A geometric construction of generalized q-Schur algebras

Representation Theory 2013-11-06 v2 Quantum Algebra

Abstract

We show that the algebras constructed in [Li10] and [Li12] are generalized q-Schur algebras as defined in [D03]. This provides a geometric construction of generalized q-Schur algebras in types A, D and E. We give a parameterization of Nakajima's Lagrangian quiver variety of type D associated to a certain highest weight.
