Quantum algebra from generalized q-Hermite polynomials

Abstract

In this paper, we discuss new results related to the generalized discrete $q$-Hermite II polynomials $ \tilde h_{n,\alpha}(x;q)$, introduced by Mezlini et al. in 2014. Our aim is to give a continuous orthogonality relation, a $q$-integral representation and an evaluation at unity of the Poisson kernel, for these polynomials. Furthermore, we introduce $q$-Schr\"{o}dinger operators and give the raising and lowering operator algebra corresponding to these polynomials. Our results generate a new explicit realization of the quantum algebra $\mathsf{su}_{q}(1, 1)$, using the generators associated with a $q$-deformed generalized para-Bose oscillator.
