Perfect state transfer in two dimensions and the bivariate dual-Hahn polynomials [PDF]

open access: yes, 2020
A new solvable two-dimensional spin lattice model defined on a regular grid of triangular shape is proposed. The hopping amplitudes between sites are related to recurrence coefficients of certain bivariate dual-Hahn polynomials.

Some homogeneous q-difference operators and the associated generalized Hahn polynomials [PDF]

open access: yesApplied Set-Valued Analysis and Optimization, 2019
In this paper, we first construct the homogeneous $q$-shift operator $\widetilde{E}(a,b;D_{q})$ and the homogeneous $q$-difference operator $\widetilde{L}(a,b; \theta_{xy})$. We then apply these operators in order to represent and investigate generalized

A discrete orthogonal polynomials approach for fractional optimal control problems with time delay [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2019
An efficient direct and numerical method has been proposed to approximate a solution of time-delay fractional optimal control problems. First, a class of discrete orthogonal polynomials, called Hahn polynomials, has been introduced and their properties ...

Moments of generalized Cauchy random matrices and continuous-Hahn polynomials [PDF]

open access: yes, 2020
In this paper we prove that, after an appropriate rescaling, the sum of moments EN(s)Tr|H|2k+2+|H|2k of an N × N Hermitian matrix H sampled according to the generalized Cauchy (also known as Hua–Pickrell) ensemble with parameter s > 0 is a continuous ...

Analysing Effects of Birth Order on Intelligence, Educational Attainment, Big Five, and Risk Aversion in an Indonesian Sample

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract Few studies have examined birth order effects on personality in countries that are not Western, educated, industrialized, rich, and democratic (WEIRD). However, theories have generally suggested that interculturally universal family dynamics are the mechanism behind birth order effects, and prominent theories such as resource dilution would ...

Coupling coefficients of suq(1,1) and multivariate q-Racah polynomials

open access: yesNuclear Physics B, 2018
Gasper & Rahman's multivariate q-Racah polynomials are shown to arise as connection coefficients between families of multivariate q-Hahn or q-Jacobi polynomials. The families of q-Hahn polynomials are constructed as nested Clebsch–Gordan coefficients

A Non-Standard Generating Function for Continuous Dual $q$-Hahn polynomials

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2011
We study a non-standard form of generating function for the three-parameter continuous dual q-Hahn polynomials $p_{n} (x; a, b, | q)$, which has surfaced in a recent work of the present authors on the construction of lifting $q$-difference operators in ...

A Survey on q-Polynomials and their Orthogonality Properties [PDF]

open access: yes, 2010
In this paper we study the orthogonality conditions satisfied by the classical q-orthogonal polynomials that are located at the top of the q-Hahn tableau (big q-jacobi polynomials (bqJ)) and the Nikiforov-Uvarov tableau (Askey-Wilson polynomials (AW ...

The Cauchy Operator and the Homogeneous Hahn Polynomials

open access: yesAmerican Journal of Applied Mathematics, 2021
The Cauchy operator plays important roles in the theory of basic hypergeometric series. As some applications, our purpose is mainly to show new proofs of the Mehler’s formula, the Rogers formula and the generating function for the homogeneous Hahn ...

Laguerre–Freud Equations for the Gauss Hypergeometric Discrete Orthogonal Polynomials

open access: yesMathematics, 2023
The Cholesky factorization of the moment matrix is considered for the Gauss hypergeometric discrete orthogonal polynomials. This family of discrete orthogonal polynomials has a weight with first moment given by ρ0=2F1a,bc+1;η.
