摘要 利用复函数结构变换的方法,考察了Schwarz-Pick引理的变换形式,得到了结构复微分与广义复梯度的表述形式,导出了具有普遍性的\,与结构函数s有关的广义Schwarz-Pick引理.极大地推广了Schwarz-Pick引理的研究范围与相关结论的普遍适用性. The transformation form of Schwarz-Pick lemma was investigated by using the method of structural transformation of complex functions. The expressions of structural complex differential and generalized complex gradient were obtained. The generalized Schwarz-Pick lemma related to structural functions was derived. It greatly enlarged the scope of Schwarz-Pick lemma reseach and the universal applicability of relevant conclusions.
