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

Abstract
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 equationFile in questo prodotto:
