Exponent of n-Ising matter fields coupled to 2d gravity

Abstract

n-Ising spins on a random surface represented by a matrix model is studied as a model of the 2D gravity coupled to matter field with the central charge c > 1. The magnetic field is introduced to discuss the scaling exponent $\Delta$, and the value of this magnetic field exponent is estimated by the series expansion.
