摘要 在拟双曲度量空间中引入拟双曲测地线和拟双曲测地三角形的概念,并利用拟双曲测地线和拟双曲测地三角形的性质来刻画了GP-双曲空间与双曲空间的一个等价性质。 In this paper,we introduce the concepts of a quasihyperbolic geodesic and quasihyperbolic geodesic triangles in quasihyperbolic metric spaces,and obtain an equivalence property of GP-hyperbolic space and hyperbolic space in terms of the properties of quasihyperbolic geodesic and quasihyperbolic geodesic triangles.
