TiTle : Symplectic field theory and codimension2 stable Hamiltonian submanifolds

Abstract : Motivated by the goal of establishing a "symplectic sum formula" in symplectic field theory, we will discuss the intersection behavior between punctured pseudoholomorphic curves and certain symplectic hypersurfaces in a symplectization. In particular we will show that the count of such intersections is always bounded from above by a finite, topologicallydetermined quantity even though the curve, the target manifold, and the symplectic hypersurface in question are all noncompact.
