Speaker:

Donghoon Jang (Pusan National University)

Moscow-Beijing Topology Seminar

During this talk, we study symplectic/Hamiltonian circle actions on symplectic manifolds that have fixed points. We discuss when a symplectic action is Hamiltonian, and the existence of a symplectic action with fixed points, which is not Hamiltonian. We discuss classifications of a symplectic action when there are few fixed points. We discuss classifications of Hamiltonian actions in low dimensions (up to dimension 4).
