The stringy E-function of the moduli space of Higgs bundles with trivial determinant
arXiv:math/0507007
Abstract
Let M be the moduli space of semistable rank 2 Higgs pairs (V,ϕ) with trivial determinant over a smooth projective curve X of genus g>1. We compute the stringy E-function of M and prove that there does not exist a symplectic desingularization of M for g>2.
