作为拟共形映射的推广,Visl引入了CQH同胚映射的概念.作者利用拟近测地线和固态弧,得到了CQH同胚映射的一个特征.此结果说明Visl提出的相关猜测在R~n中的答案是肯定的.
As a generalization of quasiconformal mappings,Visl introduced CQH home-omorphisms. The author obtains a characterization for this class of homeomorphisms in R~n in terms of neargeodesics and solid arcs.This result shows that the answer to a conjecture presented recently by Visl is affirmative in R~n.
