On a functional equation connected with Ptolemaic inequality



Abstract

In the first part of the present paper we consider Ptolemaic inequality and give some necessary conditions for its solutions. The other part is devoted to solution of some functional equation which, simultaneously, satisfies the Ptolemaic inequality.
