摘要 In this article,the author extends the validity of a uniform asymptotic expansion of the Hermite polynomials Hn(√2n+1α)to include all positive values of α. His method makes use of the rational functions introduced by Olde Daalhuis and Temme (SIAM J.Math.Anal.,(1994),25:304-321).A new estimate for the remainder is given.
