等阶等幅角Hankel函数和Bessel函数的复活性质

The resurgence properties of the Hankel and Bessel functions of nearly equal order and argument

Gergő Nemes

摘要:

本文的目的是利用M. V. Berry和C. J. Howls(Berry and Howls,Proc. R.长索克A 434(1991)657- 675)。使用这些表示,我们得到了一些性质的渐近展开的Hankel和Bessel函数及其衍生物的几乎相同的顺序和参数,包括明确的和数值计算的误差界,渐近的后期系数,指数改进的渐近展开,和光滑过渡的Stokes间断。

英文摘要:

The aim of this paper is to derive new representations for the Hankel functions, the Bessel functions and their derivatives, exploiting the reformulation of the method of steepest descents by M. V. Berry and C. J. Howls (Berry and Howls, Proc. R. Soc. Lond. A 434 (1991) 657--675). Using these representations, we obtain a number of properties of the asymptotic expansions of the Hankel and Bessel functions and their derivatives of nearly equal order and argument, including explicit and numerically computable error bounds, asymptotics for the late coefficients, exponentially improved asymptotic expansions, and the smooth transition of the Stokes discontinuities.
