Poisson maps between character varieties: gluing and capping
Indranil Biswas, Jacques Hurtubise, Lisa C. Jeffrey +1
Let G be a compact Lie group or a complex reductive affine algebraic group. We explore induced mappings between G-character varieties of surface groups by mappings between correspo…
Spectral curves for the triple reduced product of coadjoint orbits for SU(3)
Jacques Hurtubise, Lisa Jeffrey, Steven Rayan +2
We give an identification of the triple reduced product of three coadjoint orbits in SU(3) with a space of Hitchin pairs over a genus 0 curve with three punctures, where the residu…
Surjectivity of the hyperkähler Kirwan map
Jonathan Fisher, Lisa Jeffrey, Young-Hoon Kiem +2
We study a class of group actions on hyperkähler manifolds which we call actions of linear type. If is a hyperkähler manifold possessing such a -action, the hyperkähler Kirw…
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…
Cohomology pairings on singular quotients in geometric invariant theory
Lisa C. Jeffrey, Young-Hoon Kiem, Frances Kirwan +1
In this paper we shall give formulas for the pairings of intersection cohomology classes of complementary dimensions in the intersection cohomology of geometric invariant theoretic…
The Verlinde formula for parabolic bundles
Lisa C. Jeffrey
The moduli space M(n,d) is an algebraic variety parametrizing those representations of the fundamental group of a punctured Riemann surface into the Lie group SU(n) for which a loo…
