Description
I will associate, to every pair of smooth transversal Lagrangian spheres in a symplectic manifold having vanishing first Chern class, its Floer cohomology groups. Hamiltonian isotopic spheres give rise to isomorphic groups. In order to define these Floer cohomology groups, I will make a key use of symplectic field theory.
