Piunikhin, S.; Salamon, D.; Schwarz, M. Symplectic Floer-Donaldson theory and quantum cohomology. (English) Zbl 0874.53031 Thomas, C. B. (ed.), Contact and symplectic geometry. Cambridge: Cambridge University Press. Publ. Newton Inst. 8, 171-200 (1996). 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.For the entire collection see [Zbl 0852.00028].
