Shortening the Hofer length of Hamiltonian circle actions
Yael Karshon, Jennifer Slimowitz
A Hamiltonian circle action on a compact symplectic manifold is known to be a closed geodesic with respect to the Hofer metric on the group of Hamiltonian diffeomorphisms. If the m…

Convexity package for momentum maps on contact manifolds
River Chiang, Yael Karshon
Let a torus T act effectively on a compact connected cooriented contact manifold, and let Psi be the natural momentum map on the symplectization. We prove that, if dim T > 2, the u…

Non-Compact Symplectic Toric Manifolds
Yael Karshon, Eugene Lerman
A key result in equivariant symplectic geometry is Delzant's classification of compact connected symplectic toric manifolds. The moment map induces an embedding of the quotient of…
