Abstract:
Schur and q-Schur algebras are usual referred to type A. In this talk we offer a generalization which makes sense for any finite type A-G . The general q-Schur algebras afford both algebraic and geometric constructions; they have canonical bases with positivity and are closely related to the BGG category O. This is joint work with Li LUO.
