Title:  Semisymplectic group actions

Speaker: James Montaldi, INLN Nice

Abstract:  
A semisymplectic group action is one on a symplectic
manifold, where some of the elements act by reversing the symplectic
form while others preserve it. In this talk I will be presenting some joint
work with Mark Roberts on the basic properties of such actions, and how
they behave under symplectic reduction.
