M\"obius metric in sector domains

Metric Geometry 2023-03-16 v2

Abstract

The M\"obius metric δG\delta_G is studied in the cases where its domain GG is an open sector of the complex plane. We introduce upper and lower bounds for this metric in terms of the hyperbolic metric and the angle of the sector, and then use these results to find bounds for the distortion of the M\"obius metric under quasiregular mappings defined in sector domains. Furthermore, we numerically study the M\"obius metric and its connection to the hyperbolic metric in polygon domains.
