摘要

本文分析了一般三次函数逼近在原点上具有给定幂级数展开式的函数的局部性质。证明了一般三次hermite - pad形式总是定义一个三次函数，并且该函数在原点的邻域中是解析的。即使原点是函数的临界点(即，判别式在原点处为零)，这个结果也成立。

Existence and local behavior of general cubic Hermite-Padé Approximation

This paper analyses the local behavior of the general cubic function approximation to a function which has a given power series expansion about the origin. It is shown that the general cubic Hermite-Padé form always defines a cubic function and that this function is analytic in a neighbourhood of the origin. This result holds even if the origin is a critical point of the function (i.e., the discriminant has a zero at the origin).
