On zeros of quasi-orthogonal Meixner polynomials

AS Jooste, K Jordaan - arXiv preprint arXiv:2302.04193, 2023 - arxiv.org
For each fixed value of $\beta $ in the range $-2<\beta<-1$ and $0< c< 1$, we investigate
interlacing properties of the zeros of polynomials of consecutive degree for $ M_ {n}(x;\beta …

[PDF][PDF] A new symmetric endomorphism operator for some generalizations of certain generating functions

A Boussayoud, A Abderrezzak, S Araci - Notes Number Theory Discrete …, 2018 - nntdm.net
In this article, we introduce new symmetric endomorphism operators by making use of
appropriate infinite product series. The main results show that after direct calculations, the …

Interlacing of zeros of quasi-orthogonal Meixner polynomials

K Driver, A Jooste - Quaestiones Mathematicae, 2017 - Taylor & Francis
We consider the interlacing of zeros of polynomials within the sequences of quasi-
orthogonal order one Meixner polynomials characterised by− β, c∈(0, 1). The interlacing of …

On Certain Properties and Applications of the Perturbed Meixner–Pollaczek Weight

AS Kelil, AS Jooste, AR Appadu - Mathematics, 2021 - mdpi.com
This paper deals with monic orthogonal polynomials orthogonal with a perturbation of
classical Meixner–Pollaczek measure. These polynomials, called Perturbed Meixner …

Quasi-orthogonality of some hypergeometric and q-hypergeometric polynomials

DD Tcheutia, AS Jooste, W Koepf - SIGMA. Symmetry, Integrability and …, 2018 - emis.de
We show how to obtain linear combinations of polynomials in an orthogonal sequence
$\{P_n\} _ {n\geq 0} $, such as $ Q_ {n, k}(x)=\sum\limits_ {i= 0}^ k a_ {n, i} P_ {ni}(x) $, $ a …

We state and prove the q-extension of a result due to Johnston and Jordaan (cf. Johnston
and Jordaan (2015)) and make use of this result, the orthogonality of q-Laguerre, little q …
