Resumo

In this talk, we will present the Hilbert series of the graded algebra of real regular functions on the symplectic quotient associated to an SU2-module and an explicit expression for the first nonzero coefficient of the Laurent expansion of this Hilbert series at t = 1. We will provide an outline of the used techniques for our calculations, and will discuss some of our related results on Hilbert series. This is joint work with Hans-Christian Herbig (UFRJ) and Christopher Seaton (Rhodes College).
