The /N=2 U/(N) gauge theory prepotential and periods from a perturbative matrix model calculation
Abstract
We perform a completely perturbative matrix model calculation of the physical lowenergy quantities of the N=2 U( N) gauge theory. Within the matrix model framework we propose a perturbative definition of the periods a_{i} in terms of certain tadpole diagrams, and check our conjecture up to first order in the gauge theory instanton expansion. The prescription does not require knowledge of the SeibergWitten differential or curve. We also compute the N=2 prepotential F(a) perturbatively up to the firstinstanton level, finding agreement with the known result.
