چکیده
We study bivariate orthogonal polynomials associated with Freud weight functions depending on real parameters. analyse relations between the matrix coefficients of three term for orthonormal as well structure satisfied by these semiclassical polynomials, also a differential-difference equation is deduced. The extension Painlevé to case and two dimensional version Langmuir lattice are obtained.

Orthogonal matrix polynomials satisfying second order difference equations
We develop a method that allows us to construct families of orthogonal matrix polynomials of size N ×N satisfying second order difference equations with polynomial coefficients. The existence (and properties) of these orthogonal families strongly depends on the non commutativity of the matrix product, the existence of singular matrices and the matrix size N .
متن کاملOrthogonal matrix polynomials, scalar-type Rodrigues' formulas and Pearson equations
Some families of orthogonal matrix polynomials satisfying second order differential equations with coefficients independent of n have recently been introduced (see [DG1]). An important difference with the scalar classical families of Jacobi, Laguerre and Hermite, is that these matrix families do not satisfy scalar type Rodrigues’ formulas of the type (ΦnW )W, where Φ is a matrix polynomial of d...
متن کاملPainlevé V and a Pollaczek-Jacobi type orthogonal polynomials
We study a sequence of polynomials orthogonal with respect to a one parameter family of weights w(x) := w(x, t) = e x(1− x) , t ≥ 0, defined for x ∈ [0, 1]. If t = 0, this reduces to a shifted Jacobi weight. Our ladder operator formalism and the associated compatibility conditions give an easy determination of the recurrence coefficients. For t > 0, the factor e−t/x induces an infinitely strong...
متن کاملTwo variable orthogonal polynomials and structured matrices
We consider bivariate real valued polynomials orthogonal with respect to a positive linear functional. The lexicographical and reverse lexicographical orderings are used to order the monomials. Recurrence formulas are derived between polynomials of different degrees. These formulas link the orthogonal polynomials constructed using the lexicographical ordering with those constructed using the re...
