A Gromov Hyperbolic metric and Möbius transformations
Xiaoxue Xu, Gendi Wang, Xiaohui Zhang
We compare a Gromov hyperbolic metric with the hyperbolic metric in the unit ball or in the upper half space, and prove sharp comparison inequalities between the Gromov hyperbolic…
Remarks on the scale invariant Cassinian metric
Gendi Wang, Xiaoxue Xu, Matti Vuorinen
We study the geometry of the scale invariant Cassinian metric and prove sharp comparison inequalities between this metric and the hyperbolic metric in the case when the domain is e…
On Quasi-inversions
David Kalaj, Matti Vuorinen, Gendi Wang
Given a bounded domain strictly starlike with respect to we define a quasi-inversion w.r.t. the boundary We show that the qu…
Sharp Lipschitz constants for the distance ratio metric
Slavko Simić, Matti Vuorinen, Gendi Wang
We study expansion/contraction properties of some common classes of mappings of the Euclidean space with respect to the distance ratio metric. The first…
