The stringy E-function of the moduli space of Higgs bundles with trivial determinant
Young-Hoon Kiem, Sang-Bum Yoo
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…
On the existence of a crepant resolution of some moduli spaces of sheaves on an abelian surface
Jaeyoo Choy, Young-Hoon Kiem
Let J be an abelian surface with a generic ample line bundle O(1). For n>0, the moduli space M(2, 0, 2n) of O(1)-semistable sheaves F of rank 2 with Chern classes c_1(F) = 0, c_2(F…
Intersection pairings on singular moduli spaces of bundles over a Riemann surface and their partial desingularisations
Lisa C. Jeffrey, Young-Hoon Kiem, Frances C. Kirwan +1
This paper studies intersection theory on the compactified moduli space M(n,d) of holomorphic bundles of rank n and degree d over a fixed compact Riemann surface of genus g > 1 whe…
Nonexistence of a crepant resolution of some moduli spaces of sheaves on a K3 surface
Jaeyoo Choy, Young-Hoon Kiem
Let be the moduli space of O(1)-semistable rank 2 torsion-free sheaves with Chern classes and on a K3 surface where O(1) is a generic ample line…
