Query: Virtual intersections on the Quot-scheme and Vafa-Intriligator formulas   We construct a virtual fundamental class on the Quot scheme parametrizing
quotients of a trivial bundle on a curve. We use the virtual localization
formula to calculate virtual intersection numbers on Quot. As a consequence, we
reprove the Vafa-Intriligator formula; our answer is valid even when the Quot
scheme is badly behaved. More intersections are computed by the same method.
Finally, we present an application to the non-vanishing of the Pontrjagin ring
of the moduli space of bundles.
