Surjectivity for Hamiltonian Loop Group Spacees
Raoul Bott, Susan Tolman, Jonathan Weitsman
Let be a compact Lie group, and let denote the corresponding loop group. Let be a weakly symplectic Banach manifold. Consider a Hamiltonian action of on $(X,ω…

Maximal Hamiltonian tori for polygon spaces
Jean-Claude Hausmann, Susan Tolman
We study the poset of Hamiltonian tori for polygon spaces. We determine some maximal elements and give examples where maximal Hamiltonian tori are not all of the same dimension.

Complete invariants for Hamiltonian torus actions with two dimensional quotients
Yael Karshon, Susan Tolman
We study torus actions on symplectic manifolds with proper moment maps in the case that each reduced space is two-dimensional. We provide a complete set of invariants for such spac…
