报告摘要  Abstract

We first discuss the Slodowy-McKay correspondence between all twisted affine Dynkin diagrams and pairs of nontrivial subgroups of SU(2), and then compute the Poincare series of the tensor algebra T(V) for all irreducible module V of the finite subgroup. The exact formula is then shown to provide a conceptual information about the exponents of the affine Lie algebras.
