摘要

We study a hyperbolic-type metric hG,c introduced by Dovgoshey, Hariri, and Vuorinen and determine the best constant c > 0 for which this function hG,c is a metric in specifically chosen G. We also present several sharp inequalities between hG,c and other hyperbolic-type metrics and offer several results obtained for a ball inclusion.
