Shiga, Hiroshige Riemann mappings of invariant components of Kleinian groups. (English) Zbl 1184.30036 J. Lond. Math. Soc., II. Ser. 80, No. 3, 716-728 (2009). The author investigates complex analytic properties of Riemann mappings of simply connected invariant components of Kleinian groups. In particular, he considers the growth of the derivatives of Riemann mappings to understand Kleinian groups that are quasi-Fuchsian groups, regular \(b\)-groups, and Kleinian groups with bounded geometry.Theorem 1.1. Let \(G\) be a finite generated non-elementary Kleinian group with an invariant component \(\Omega_{0}.\) Then, the following conditions are equivalent:(1) \(\Omega_{0}\) is a Hölder domain;(2) \(\Omega_{0}\) is a John domain;(3) \(G\) is geometrically finite and a parabolic element stabilizes a round disk in \(\Omega_{0}\). Furthermore, if \(\Omega_{0}\) is simply connected, then \(\Omega_{0}\) is a Hölder domain if and only if it is a quasi-disk. Hence, \(G\) is a quasi-Fuchsian group. Reviewer: V. V.
