摘要

前言/目的:本文考虑了鞍点近似方法。方法:鞍点法被应用于数学和物理的几个不同领域。阶乘函数展开式的几个项已经被明确地计算出来了。结果:用这种方法求得的积分值接近准确值。结论:高阶校正是不可忽略的，即使需要中等水平的精度。

Saddle point approximation to Higher order

Introduction/purpose: Saddle point approximation has been considered in the paper Methods: The saddle point method is used in several different fields of mathematics and physics. Several terms of the expansion for the factorial function have been explicitely computed. Results: The integrals estimated in this way have values close to the exact one. Conclusions: Higher order corrections are not negligible even when requiring moderate levels of precision.
