转折点展开的精确误差界

Sharp error bounds for turning point expansions

T. M. Dunster, A. Gil, J. Segura

摘要:

本文导出了具有简单转向点的线性微分方程渐近展开式的可计算的精确误差界。展开式涉及Airy函数和缓变系数函数。的界限的清晰度示出数值与应用程序的大阶贝塞尔函数。

英文摘要:

Computable and sharp error bounds are derived for asymptotic expansions for linear differential equations having a simple turning point. The expansions involve Airy functions and slowly varying coefficient functions. The sharpness of the bounds is illustrated numerically with an application to Bessel functions of large order.
