A generating function and formulae defining the first-associated Meixner-Pollaczek polynomials

Abstract

While considering nonlinear coherent states with specific anti-holomorphic coefficients ${\bar{z}}^n/\sqrt{x_n!}$, we identify as first associated Meixner-Pollaczek polynomials the orthogonal polynomials arising from shift operators which are defined by the sequence $x_n=(n+1{)}^2$ . We give a formula defining these polynomials by writing down their generating function. This also leads to construct a Bargmann-type integral transform whose kernel is given in terms of a ${\Psi }_1$ Humbert's function.
