Loop Equations for the d-dimensional n-Hermitian matrix model

Abstract

We derive the loop equations for the d-dimensional n-Hermitian matrix model. These are a consequence of the Schwinger-Dyson equations of the model. Moreover we show that in leading order of large $N$ the loop equations form a closed set. In particular we derive the loop equations for the $n=2^k$ matrix model recently proposed to describe the coupling of Two-dimensional quantum gravity to conformal matter with $c>1$.
