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…

Bundles over Connected Sums

Lisa C Jeffrey, Paul Selick

A principal bundle over the connected sum of two manifolds need not be diffeomorphic or even homotopy equivalent to a non-trivial connected sum of manifolds. We show however that t…

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…

Explicit Poincaré duality in the cohomology ring of the SU(2) character variety of a surface

Lisa Jeffrey, Aidan Lindberg, Steven Rayan

We provide an explicit description of the Poincaré dual of each generator of the rational cohomology ring of the character variety for a genus surface with central exte…

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.
