On nearly semifree circle actions
Dusa McDuff, Susan Tolman
Recall that an effective circle action is semifree if the stabilizer subgroup of each point is connected. We show that if $(M, \om)$ is a coadjoint orbit of a compact Lie group …
Topological properties of Hamiltonian circle actions
Dusa McDuff, Susan Tolman
This paper studies Hamiltonian circle actions, i.e. circle subgroups of the group Ham(M,\om) of Hamiltonian symplectomorphisms of a closed symplectic manifold (M,\om). Our main too…
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…
Centered complexity one Hamiltonian torus actions
Yael Karshon, Susan Tolman
We consider symplectic manifolds with Hamiltonian torus actions which are "almost but not quite completely integrable": the dimension of the torus is one less than half the dimensi…
