The Algebra Seminar this Friday 29 July will be given by Jie Du. --------------------------------------------------------------------------- Speaker: Jie Du (University of New South Wales) Date: Friday 29 July Time: 12.05-12.55pm Venue: Carslaw 175 Title: A double Hall approach to affine q-Schur algebras Abstract: I will talk about the structure of the double Ringel-Hall algebras associated with cyclic quivers and their connection with affine q-Schur algebras. This includes the Drinfeld-Jimbo type presentation, the quantum loop algebra interpretation, the affine quantum Schur-Weyl duality, the structure of affine q-Schur algebras and connections with various existing works by Lusztig, Schiffmann, Hubery, Varaganolo-Vasserot, McGerty, etc. I will also mention possible Beilinson-Lusztig-MacPherson type realization and Lusztig type integral forms. Representations of affine q-Schur algebras will probably be briefly discussed. This is joint work with Bangming Deng and Qiang Fu. ----------------------------------------------------------------------------
