Ordered Products, $W_{\infty}$-Algebra, and Two-Variable, Definite-Parity, Orthogonal Polynomials

open access: yes, 1997
It has been shown that the Cartan subalgebra of $W_{\infty}$- algebra is the space of the two-variable, definite-parity polynomials. Explicit expressions of these polynomials, and their basic properties are presented.

Deformed su(1,1) Algebra as a Model for Quantum Oscillators

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The Lie algebra su(1,1) can be deformed by a reflection operator, in such a way that the positive discrete series representations of su}(1,1) can be extended to representations of this deformed algebra su(1,1)_gamma.

Appell polynomials and their relatives II. Boolean theory

open access: yes, 2007
The Appell-type polynomial family corresponding to the simplest non-commutative derivative operator turns out to be connected with the Boolean probability theory, the simplest of the three universal non-commutative probability theories (the other two ...

Asymptotics of Meixner polynomials and Christoffel–Darboux kernels [PDF]

open access: yesTransactions of the Moscow Mathematical Society, 2013
Summary: We obtain the asymptotics of the classical Meixner polynomials \(M_n(x)\) (orthogonal with respect to a discrete measure supported at the nonnegative integer points) and the corresponding reproducing kernels (Christoffel-Darboux kernels) \(K_n(x,y)\) as \(n\) and the variable \(x\) tend to infinity under various relationships between their ...

On some applications of a symbolic representation of non-centered L\'evy processes

open access: yes, 2013
By using a symbolic technique known in the literature as the classical umbral calculus, we characterize two classes of polynomials related to L\'evy processes: the Kailath-Segall and the time-space harmonic polynomials.

A new class of coherent states with Meixner-Pollaczek polynomials for the Gol'dman-Krivchenkov Hamiltonian

open access: yes, 2010
A class of generalized coherent states with a new type of the identity resolution are constructed by replacing the labeling parameter zn/n! of the canonical coherent states by Meixner-Pollaczek polynomials with specific parameters.
