Abstract

An infinite asymptotic expansion is derived for the Meixner-Pollaczek polynomials Mn (nα; δ, η) as n → ∞, which holds uniformly for -M ≤ α ≤ α M, where M can be any positive number. This expansion involves the parabolic cylinder function and its derivative. If αn, s denotes the sth zero of Mn (nα; δ, η), counted from the right, and if formula, denotes its sth zero counted from the left, then for each fxed s, three-term asymptotic approximations are obtained for both αn, s and formula, as n → ∞. © 2016 by World Scientific Publishing Co.
