Kirwan surjectivity and Lefschetz-Sommese theorems for a generalized hyperkähler reduction

Jonathan Fisher, Lisa Jeffrey, Alessandro Malusà +1

Let be a compact Lie group. We study a class of Hamiltonian -manifolds decorated with a function with certain equivariance properties, under conditions on…

Flat connections and the commutator map for SU(2)

Nan-Kuo Ho, Lisa C. Jeffrey, Paul Selick +1

We study the topology of the SU(2)-representation variety of the compact oriented surface of genus 2 with one boundary component about which the holonomy is a generator of the cent…

Poisson structure on character varieties

Indranil Biswas, Lisa C. Jeffrey

We show that the character variety for a -punctured oriented surface has a natural Poisson structure.

Intersection pairings in the N-fold reduced product of adjoint orbits

Lisa Jeffrey, Jia Ji

In previous work we computed the symplectic volume of the symplectic reduced space of the product of N adjoint orbits of a compact Lie group. In this paper we compute the intersect…

The volume of the N-fold reduced product of coadjoint orbits

Lisa Jeffrey, Jia Ji

We compute the symplectic volume of the symplectic reduced space of the product of N coadjoint orbits of a compact connected Lie group G. We compare our result with the result of S…

The SU(2)-character variety of the closed surface of genus 2

Nan-Kuo Ho, Lisa C. Jeffrey, Khoa Dang Nguyen +1

We study the symplectic geometry of the SU(2)-representation variety of the compact oriented surface of genus 2. We use the Goldman flows to identify subsets of the moduli space wi…
