Abstract:
We study SYM gauge theories living on ALE spaces. Using localization formulae we compute the prepotential (and its gravitational corrections) for SU(N) supersymmetric N=2,2{\cal N}=2, 2^* gauge theories on ALE spaces of the AnA_n type. Furthermore we derive the Poincar\'{e} polynomial describing the homologies of the corresponding moduli spaces of self-dual gauge connections. From these results we extract the N=4{\cal N}=4 partition function which is a modular form in agreement with the expectations of SL(2,Z)SL(2,\Z) duality.
