Abstract

In this paper we provide necessary and sufficient conditions for a formal power series g over R or C to have formal power series g1/k such that (g1/k)k=g for all positive integers k or for some positive integers. The algorithms of computing such formal root series are also provided. Moreover, we investigate the uniqueness of formal root series if there exists.

形式乘法根级数及其评估算法

摘要

在本文中,我们提供了一个正式的幂级数 g 的充要条件 电阻 或者 C 有正式的幂级数 G1/ 以至于 (G1/)=G对于所有正整数 k 或某些正整数。还提供了计算这种形式根系列的算法。此外,如果存在,我们调查形式根系列的唯一性。
