Abstract

We compute the Hilbert series of the graded algebra of real regular functions on a linear symplectic quotient by the 22-torus as well as the first four coefficients of the Laurent expansion of this Hilbert series at t=1t = 1. We describe an algorithm to compute the Hilbert series as well as the Laurent coefficients in explicit examples.
