TITLE | Cyclic Actions on Symplectic 4-Manifolds |
ABSTRACT | We study homologically trivial finite cyclic actions on symplectic four-manifolds and discuss whether they extend to circle actions. In particular, we give examples of cyclic actions that do not extend to circle actions, while the manifolds themselves admit circle actions. This is a joint work with Liat Kessler. |
