Generalization of matching extensions in graphs—combinatorial interpretation of orthogonal and q-orthogonal polynomials [PDF]

open access: yes, 2005
In this paper, we present generalization of matching extensions in graphs and we derive combinatorial interpretation of wide classes of orthogonal and q-orthogonal polynomials. Specifically, we assign general weights to complete graphs, cycles and chains

Jacobi polynomials and generalized Clifford algebra-valued Appell sequences [PDF]

open access: yes, 2014
: Appell sequences in Clifford analysis are defined as polynomial families on which the Heisenberg algebra acts through a raising and a lowering operator satisfying the canonical Heisenberg relation. Recently, these sequences have gained new interest, as

A prospective study of the k-factor Gegenbauer processes with heteroscedastic errors and an application to inflation rates [PDF]

open access: yes
We investigate some statistical properties of the new k-factor Gegenbauer process with heteroscedastic noises One of the goals of the paper is to give tools which permit to use this model to explain the behaviour of certain data sets in finance and in ...

A “Continuous ” Limit of the Complementary Bannai–Ito Polynomials: Chihara Polynomials [PDF]

open access: yes, 2014
. A novel family of −1 orthogonal polynomials called the Chihara polynomials is characterized. The polynomials are obtained from a “continuous ” limit of the comple-mentary Bannai–Ito polynomials, which are the kernel partners of the Bannai–Ito polyno ...

New Generating Functions for Chebyshev, Gegenbauer, and Jacobi Matrix Polynomials

open access: yesMediterranean Journal of Mathematics
Abstract This paper presents a unified approach to deriving generating functions for the important class of matrix analogues of the Chebyshev, Gegenbauer, and Jacobi polynomials. Alongside these results, we also establish several explicit identities for the corresponding scalar polynomial families, which, to the best of our knowledge,
