摘要
利用双曲复平面上M inkowsk i圆的性质,引入双曲复平面上类时邻域(类空邻域,类光邻域)的概念,讨论了类时邻域的性质,得到类时曲线的有限覆盖定理.
This paper introduces the concepts of the time-like neighborhood（space-like neighborhood and light-like neighborhood） by using the properties of Minkowski circle on the hyperbolic complex plane,using for discussing the properties of the time-like neighborhood.The theorem of finite covering of time-like curve is given.
