Abstract
Expansions in the elgenfunctions of the Sturm-Liouville problem and perturbation expansions are applied to obtain asymptotic formulas for parabolic cylindrical functions and Hermite polynomials for large n. The formulas are compared with previously published formulas and, in particular, a numerical comparison is made for one Hermite polynomial.
