Seiberg-Witten Prepotential from Instanton Counting
Pages: 831 – 864
Direct evaluation of the Seiberg-Witten prepotential is accomplished following the localization programme suggested in . Our results agree with all low-instanton calculations available in the literature. We present a two-parameter generalization of the Seiberg-Witten prepotential, which is rather natural from the M-theory/five dimensional perspective, and conjecture its relation to the tau-functions of KP/Toda hierarchy.
