Geometric Charaterizations of Neargeodesic Annular Quasiconvexity for Quasihyperbolic Metric Spaces
In this paper,we introduce the concepts of inversion metric and sphericaliza-tion matric in quasihyperbolic metric spaces,and obtain some geometric characterizations of neargeodesic annular quasiconvexity for quasihyperbolic metric spaces in terms of the properties of inversion metric and sphericalization matric.
