چکیده
Relation between the Virasoro constraints and KP integrability (determinant formulas) for matrix models is a lasting mystery. We elaborate on claim that situation improved when enhanced to super-integrability, i.e. explicit formulas Gaussian averages of characters. In this case, are equivalent simple recursive formulas, which have appropriate combinations characters as their solutions. Moreover, one can easily separate dependence size matrix, deduce superintegrability from constraints. describe ways do so Hermitian model. The result spectacularly elegant reformulation identities Schur functions evaluated at loci in space time-variables.

Pseudo-Hermitian ensemble of random Gaussian matrices.
It is shown how pseudo-Hermiticity, a necessary condition satisfied by operators of PT symmetric systems can be introduced in the three Gaussian classes of random matrix theory. The model describes transitions from real eigenvalues to a situation in which, apart from a residual number, the eigenvalues are complex conjugate.

In this paper we use a generalization of Oevel’s theorem about master symmetries to relate them with superintegrability and quadratic algebras.
متن کاملImage Segmentation using Gaussian Mixture Model
Abstract: Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we used Gaussian mixture model to the pixels of an image. The parameters of the model were estimated by EM-algorithm. In addition pixel labeling corresponded to each pixel of true image was made by Bayes rule. In fact,...
متن کاملn-Hermitian Matrix model
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 matrix model recently proposed to describe the coupling of Two-dimensional quantum gravity to conformal ...
متن کاملThe Calogero Model and the Virasoro Symmetry
We construct new realizations of the Virasoro algebra inspired by the Calogero model. The Virasoro algebra we find acts as a kind of spectrum-generating algebra of the Calogero model. We furthermore present the su-perextension of these results and introduce a class of higher-spin extensions of the Virasoro algebra which are of the W ∞-type.
