Operator orderings and Meixner-Pollaczek polynomials [PDF]

open access: yesJournal of Mathematical Physics, 2013
The aim of this paper is to give identities which are generalizations of the formulas given by Koornwinder [J. Math. Phys. 30, 767–769 (1989)]10.1063/1.528394 and Hamdi-Zeng [J. Math. Phys. 51, 043506 (2010)]10.1063/1.3372526. Our proofs are much simpler than and different from the previous investigations.

Discrete semi-classical orthogonal polynomials: Generalized Meixner

open access: yesJournal of Approximation Theory, 1986
The property of quasiorthogonality of the derivative of semi classical orthogonal is extended to the discrete case for the generalized Meixner polynomials. The positive weigth \(\rho\) (x) is solution of the difference equation A(x) \(\rho\) (x\(+1)-B(x) \rho (x)=0\) with A(x) and B(x) polynomials of degree respectively \(\alpha\) and \(\beta\).

Lie-algebraic discretization of differential equations

open access: yes, 1995
A certain representation for the Heisenberg algebra in finite-difference operators is established. The Lie-algebraic procedure of discretization of differential equations with isospectral property is proposed. Using $sl_2$-algebra based approach, (quasi)-

Spectral Analysis of Certain Schrödinger Operators

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The J-matrix method is extended to difference and q-difference operators and is applied to several explicit differential, difference, q-difference and second order Askey-Wilson type operators.

Orthogonal polynomials on a bi-lattice

open access: yes, 2010
We investigate generalizations of the Charlier and the Meixner polynomials on the lattice N and on the shifted lattice N+1-\beta. We combine both lattices to obtain the bi-lattice N \cup (N+1-\beta) and show that the orthogonal polynomials on this bi ...

Meixner polynomials and nonvanishing holomorphic functions

open access: yesJournal of Computational and Applied Mathematics, 2001
Let \(M_{t,\tau} (t>0,\tau\in (0,1))\) denote the class of all holomorphic functions \(f\) defined on the unit disc \(D\) = \(\{z:|z|

Convolutions for orthogonal polynomials from Lie and quantum algebra representations

open access: yes, 1996
The interpretation of the Meixner-Pollaczek, Meixner and Laguerre polynomials as overlap coefficients in the positive discrete series representations of the Lie algebra su(1,1) and the Clebsch-Gordan decomposition leads to generalisations of the ...
