Universal Ratios and Correlation Functions ∗

چکیده
We review some recent results concerning the quantitative analysis of the universality classes of two-dimensional statistical models near their critical point. We also discuss the exact calculation of the two–point correlation functions of disorder operators in a free theory of complex bosonic and fermionic field, correlators ruled by a Painlevè differential equation.

Universal Approximator Property of the Space of Hyperbolic Tangent Functions
In this paper, first the space of hyperbolic tangent functions is introduced and then the universal approximator property of this space is proved. In fact, by using this space, any nonlinear continuous function can be uniformly approximated with any degree of accuracy. Also, as an application, this space of functions is utilized to design feedback control for a nonlinear dynamical system.
متن کاملUniversal Results for Correlations of Characteristic Polynomials: Riemann-Hilbert Approach
Abstract We prove that general correlation functions of both ratios and products of characteristic polynomials of Hermitian random matrices are governed by integrable kernels of three different types: a) those constructed from orthogonal polynomials; b) constructed from Cauchy transforms of the same orthogonal polynomials and finally c) those constructed from both orthogonal polynomials and the...
متن کاملA new class of short distance universal amplitude ratios
We propose a new class of universal amplitude ratios which involve the first terms of the short distance expansion of the correlators of a statistical model in the vicinity of a critical point. We will describe the critical system with a conformal field theory (UV fixed point) perturbed by an appropriate relevant operator. In two dimensions the exact knowledge of the UV fixed point allows for a...
متن کاملUniversal random matrix correlations of ratios of characteristic polynomials at the spectral edges
It has been shown recently [10] that Cauchy transforms of orthogonal polynomials appear naturally in general correlation functions containing ratios of characteristic polynomials of random N × N Hermitian matrices. Our main goal is to investigate the issue of universality of large N asymptotics for those Cauchy transforms for a wide class of weight functions. Our analysis covers three different...
متن کاملUniversal amplitude ratios and functions for the SU(2) finite-temperature phase transition.
Universal functions and amplitude ratios associated with the classes of second order phase transitions are used as additional tests of the prediction that the pure glue, SU(2), nite-temperature, deconnning phase transition is in the universality class of the three-dimensional Ising model. Published gauge theory Monte Carlo data, give values that can be compared with theory and Ising model numer...
