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.
