Journal d’Analyse Mathématique Aims and scope

Abstract

Several qualitative properties of the conformal homeomorphisms between relative circle domains are proved. In particular, counterexamples are presented to the analog of Koebe’s 1/4-Theorem for conformai homeomorphisms between relative circle domains in simply connected domains, and for isomorphisms of disk packings.
