For semi-positive symplectic manifolds the Floer cohomology groups are naturally isomorphic to the ordinary cohomology groups. The paper outlines a new proof for this fact and shows that the isomorphism intertwines the quantum cup product in ordinary cohomology with the “pair-of-pants” product in Floer cohomology. The new proof uses a glueing theorem for J-holomorphic curves. The article provides motivations and sketches the proofs. Technical details are promised to appear elsewhere.
