Universal correlators for multi - arc complex matrix models
The correlation functions of the multi-arc complex matrix model are shown to be universal for any finite number of arcs. The universality classes are characterized by the support of the eigenvalue density and are conjectured to fall into the same classes as the ones recently found for the hermitian model. This is explicitly shown to be true for the case of two arcs, apart from the known result ...
متن کاملExact Multi-Matrix Correlators
We argue that restricted Schur polynomials provide a useful parameterization of the complete set of gauge invariant variables of multi-matrix models. The two point functions of restricted Schur polynomials are evaluated exactly in the free field theory limit. They have diagonal two point functions.
متن کاملCorrelators for the Complex Matrix Model
We describe an iterative scheme which allows us to calculate any multi-loop corre-lator for the complex matrix model to any genus using only the first in the chain of loop equations. The method works for a completely general potential and the results contain no explicit reference to the couplings. The genus g contribution to the m–loop correlator depends on a finite number of parameters, namely...
متن کاملExact correlators of two – matrix models
We compute exact solutions of two–matrix models, i.e. detailed genus by genus expressions for the correlation functions of these theories, calculated without any approximation. We distinguish between two types of models, the unconstrained and the constrained ones. Unconstrained two–matrix models represent perturbations of c = 1 string theory, while the constrained ones correspond to topological...
متن کاملBernoulli matrix approach for matrix differential models of first-order
The current paper contributes a novel framework for solving a class of linear matrix differential equations. To do so, the operational matrix of the derivative based on the shifted Bernoulli polynomials together with the collocation method are exploited to reduce the main problem to system of linear matrix equations. An error estimation of presented method is provided. Numerical experiments are...
