Abstract:
The study of fixed points of group actions is an important topic in geometry and topology. During this talk, we focus on fixed points of actions in the case where manifolds admit symplectic structures and circle actions on the manifolds preserve the symplectic structures. We discuss the classification of a symplectic circle action with fixed points, from small numbers of fixed points and from low dimensions. Next, we discuss when a symplectic circle action is Hamiltonian.
