Finite N analysis of matrix models for n-Ising spin on a random surface
Shinobu Hikami
Abstract
The saddle point equation described by the eigenvalues of N by N Hermitian matrices is analized for a finite N case and the scaling relation for the large N is considered. The critical point and the critical exponents of matrix model are obtained by the finite N scaling. One matrix model and two matrix model are studied in detail. Small N behavior for n-Ising model on a random surface is investigated.
