摘要:In this talk, we consider the operation of connected sum from two symplectic manifolds with Hamiltonian group actions along a common symplectic divisor. Under some assumptions, there exists a moment map on the sum. We show two ways to get the moment map, one is to study the normal bundles of the divisor, the other is based on cutting along a contact hypersurface. This is a joint work with Bai-Ling Wang.
