On the ω-multiple Meixner polynomials of the first kind

open access: yesJournal of Inequalities and Applications, 2020
In this study, we introduce a new family of discrete multiple orthogonal polynomials, namely ω-multiple Meixner polynomials of the first kind, where ω is a positive real number.

Orthogonal Polynomials with Singularly Perturbed Freud Weights

open access: yesEntropy, 2023
In this paper, we are concerned with polynomials that are orthogonal with respect to the singularly perturbed Freud weight functions. By using Chen and Ismail’s ladder operator approach, we derive the difference equations and differential-difference ...

Algebra of quantum C $$ \mathcal{C} $$ -polynomials

open access: yesJournal of High Energy Physics, 2021
Knot polynomials colored with symmetric representations of SL q (N) satisfy difference equations as functions of representation parameter, which look like quantization of classical A $$ \mathcal{A} $$ -polynomials.

On analytic properties of Meixner-Sobolev orthogonal polynomials of higher order difference operators

open access: yes, 2020
In this contribution we consider sequences of monic polynomials orthogonal with respect to Sobolev-type inner product \[ \left\langle f,g\right\rangle= \langle {\bf u}^{\tt M},fg\rangle+\lambda \mathscr T^j f (\alpha)\mathscr T^{j}g(\alpha), \] where ...

On difference polynomials and hereditarily irreducible polynomials

open access: yesJournal of Number Theory, 1980
AbstractA difference polynomial is one of the form P(x, y) = p(x) − q(y). Another proof is given of the fact that every difference polynomial has a connected zero set, and this theorem is applied to give an irreducibility criterion for difference polynomials. Some earlier problems about hereditarily irreducible polynomials (HIPs) are solved.

Matrix-Valued Little q-Jacobi Polynomials [PDF]

open access: yes, 2014
Matrix-valued analogues of the little q-Jacobi polynomials are introduced and studied. For the 2x2-matrix-valued little q-Jacobi polynomials explicit expressions for the orthogonality relations, Rodrigues formula, three-term recurrence relation and their

Difference dimension quasi-polynomials

open access: yesAdvances in Applied Mathematics, 2017
We consider Hilbert-type functions associated with difference (not necessarily inversive) field extensions and systems of algebraic difference equations in the case when the translations are assigned some integer weights. We will show that such functions are quasi-polynomials, which can be represented as alternative sums of Ehrhart quasi-polynomials ...

$q$-Classical orthogonal polynomials: A general difference calculus approach

open access: yes, 2009
It is well known that the classical families of orthogonal polynomials are characterized as eigenfunctions of a second order linear differential/difference operator.

An algebraic interpretation of the multivariate $q$-Krawtchouk polynomials [PDF]

open access: yes, 2015
The multivariate quantum $q$-Krawtchouk polynomials are shown to arise as matrix elements of "$q$-rotations" acting on the state vectors of many $q$-oscillators. The focus is put on the two-variable case.
