Abstract:In this talk, I will describe the center Z of the finite W-algebra U(g,e) with a semisimple Lie algebra g over an algebraically closed field k of characteristic p>0, and an arbitrarily given nilpotent element e ∈ g. For Spec(Z), we show that it is a normal variety, and its Azumaya locus coincides with its smooth locus of smooth points. The former locus reflects irreducible representations of maximal dimension for U(g,e).This is a joint work with Yang Zeng.
