On the hyperbolic distance of $n$ -times punctured spheres

Toshiyuki Sugawa, Matti Vuorinen, Tanran Zhang

The length of the shortest closed geodesic in a hyperbolic surface $X$ is called the systole of $X .$ When $X$ is an $n$ -times punctured sphere $C^∖ A$ where…

Construction of nearly hyperbolic distance on punctured spheres

Toshiyuki Sugawa, Tanran Zhang

We define a distance function on the bordered punctured disk $0 < ∣ z ∣ \leq 1/ e$ in the complex plane, which is comparable with the hyperbolic distance of the punctured unit disk $0<|z|…
