Quantum cohomology of the moduli space of stable bundles over a Riemann surface

Original · EN

We determine the quantum cohomology of the moduli space of odd degree rank two stable vector bundles over a Riemann surface Σ of any genus. This work together with dg-ga/9710029 prove that this quantum cohomology is isomorphic to the instanton Floer cohomology of the three manifold Σ× S¹. (Note: There is some overlap with the previous paper: alg-geom/9711013).
