Schwarz type lemmas for quaternion k-regular functions
摘要
In this paper, Schwarz-type lemmas for different classes of quaternion functions are obtained. Firstly, some properties of symmetric points are given. Secondly, the Schwarz-type lemma and the Schwarz-Pick-type theorem for quaternion regular functions are obtained. Finally, the Schwarz-type lemma for quaternion k-regular functions is derived.
