Non-Hamiltonian actions with fewer isolated fixed points
Donghoon Jang, Susan Tolman
In an earlier paper, the second author resolved a question of McDuff by constructing a non-Hamiltonian symplectic circle action on a closed, connected six-dimensional symplectic ma…
Symplectic circle actions with isolated fixed points
Donghoon Jang
Consider a symplectic circle action on a closed symplectic manifold with non-empty isolated fixed points. Associated to each fixed point, there are well-defined non-zero integers,…
Hamiltonian circle actions on eight dimensional manifolds with minimal fixed sets
Donghoon Jang, Susan Tolman
Consider a Hamiltonian circle action on a closed -dimensional symplectic manifold with exactly five fixed points, which is the smallest possible fixed set. In their paper, L…
Symplectic periodic flows with exactly three equilibrium points
Donghoon Jang
Let the circle act symplectically on a compact, connected symplectic manifold . If there are exactly three fixed points, is equivariantly symplectomorphic to …
