Intersection numbers in quasi-Hamiltonian reduced spaces
Lisa Jeffrey, Joon-Hyeok Song
In this paper we prove a residue formula for intersection pairings of reduced spaces of certain quasi-Hamiltonian G-spaces, by constructing the corresponding Hamiltonian G-space. O…
Localization theorems by symplectic cuts
Lisa Jeffrey, Mikhail Kogan
Given a compact symplectic manifold M with the Hamiltonian action of a torus T, let zero be a regular value of the moment map, and M_0 the symplectic reduction at zero. Denote by κ…
The volume of the moduli space of flat connections on a nonorientable 2-manifold
Lisa Jeffrey, Nan-Kuo Ho
We compute the Riemannian volume on the moduli space of flat connections on a nonorientable 2-manifold, for a natural class of metrics. We also show that Witten's volume formula fo…
Distinguishing the Chambers of the Moment Polytope
Rebecca F. Goldin, Tara S. Holm, Lisa C. Jeffrey
Let M be a compact manifold with a Hamiltonian T action and moment map Phi. The restriction map in equivariant cohomology from M to a level set Phi^{-1}(p) is a surjection, and we…
