Abstract

We study the large limit of the class of U(N) ${\CN}=1$ SUSY gauge theories with an adjoint scalar and a superpotential . In each of the vacua of the quantum theory, the expectation values $\la$Tr$\ra$ are determined by a master matrix with eigenvalue distribution . is quite distinct from the eigenvalue distribution of the corresponding large matrix model proposed by Dijkgraaf and Vafa. Nevertheless, it has a simple form on the auxiliary Riemann surface of the matrix model. Thus the underlying geometry of the matrix model leads to a definite prescription for computing , knowing .
