Some classical multiple orthogonal polynomials [PDF]
Recently there has been a renewed interest in an extension of the notion of orthogonal polynomials known as multiple orthogonal polynomials. This notion comes from simultaneous rational approximation (Hermite-Pade approximation) of a system of several ...

Classes of Bivariate Orthogonal Polynomials [PDF]
We introduce a class of orthogonal polynomials in two variables which generalizes the disc polynomials and the 2-$D$ Hermite polynomials. We identify certain interesting members of this class including a one variable generalization of the 2-$D$ Hermite ...

On a Generalisation of Hermite Polynomials [PDF]
In this paper, the author introduces a generalisation of the Hermite polynomials. Hypergeometric representations, a new generating relation and n n th order differential formulae for the generalised polynomials have also been derived therein.

Rational extensions of the quantum harmonic oscillator and exceptional Hermite polynomials [PDF]
We prove that every rational extension of the quantum harmonic oscillator that is exactly solvable by polynomials is monodromy free, and therefore can be obtained by applying a finite number of state-deleting Darboux transformations on the harmonic ...

A $q$-deformation of true-polyanalytic Bargmann transforms when $q^{-1}>1$
We combine continuous $q^{-1}$-Hermite Askey polynomials with new $2D$ orthogonal polynomials introduced by Ismail and Zhang as $q$-analogs for complex Hermite polynomials to construct a new set of coherent states depending on a nonnegative integer ...

A characterization of Hermite polynomials
AbstractWe show that for any orthogonal polynomials Pn(x)n=0∞ satisfying a spectral type differential equation of order N (⩾2) essentially Hermite polynomials if and only if the leading coefficient lN(x) is a nonzero constant.

Some Integrals Involving q-Laguerre Polynomials and Applications
The integrals involving multivariate q-Laguerre polynomials and then auxiliary ones are studied. In addition, the representations of q-Hermite polynomials by q-Laguerre polynomials and their related integrals are given.

Some relations satisfied by Hermite-Hermite matrix polynomials [PDF]
summary:The classical Hermite-Hermite matrix polynomials for commutative matrices were first studied by Metwally et al. (2008). Our goal is to derive their basic properties including the orthogonality properties and Rodrigues formula.
