Apollonian Circle Packings and Beyond: Number Theory, Graph Theory and Geometric Statistics

Xin Zhang (UIUC)

Abstract: An Apollonian circle packings (ACP) is an ancient Greek construction obtained by repeatedly inscribing circles to an original configuration of three mutually tangent circles. In the last decade, the surprisingly rich structure of ACP has attracted experts from different fields: number theory, graph theory, homogeneous dynamics, to name a few. In this talk, Iíll survey questions and the progress on this topic and related fields.
