讲座简介:
For any affine Hopf algebra H which admits a large central Hopf subalgebra, H can be endowed with a Cayley-Hamilton Hopf algebra structure in the sense of De Concini-Procesi-Reshetikhin-Rosso. By a standard fact, the irreducible representations of H is the disjoint union of the irreducible representations over its fiber algebras. The irreducible representations of H have strong relation with the (lowest) discriminant ideal of H. The talk is based on a joint work with Mi and Yakimov, and some work with Huang, Mi and Qi.
