Equivariant cohomology of a complexity-one four-manifold is determined by combinatorial data

Tara Holm, Liat Kessler

For Hamiltonian circle actions on compact, connected, four-dimensional manifolds, we give a generators and relations description for the even part of the equivariant cohomology, as…

Homologically trivial symplectic cyclic actions need not extend to Hamiltonian circle actions

River Chiang, Liat Kessler

We give examples of symplectic actions of a cyclic group, inducing a trivial action on homology, on four-manifolds that admit Hamiltonian circle actions, and show that they do not…

Cyclic actions on rational ruled symplectic four-manifolds

River Chiang, Liat Kessler

Let $(M, ω)$ be a ruled symplectic four-manifold. If $(M, ω)$ is rational, then every homologically trivial symplectic cyclic action on $(M, ω)$ is the restriction of a Hamiltonian c…
