Uniformization and Rigidity in Conformal Geometry

Sergiy A. Merenkov (University of Michigan)

Abstract: I will discuss recent results on quasisymmetric rigidity of Sierpinski carpets. One such result states that every quasisymmetric self-map of the Sierpinski carpet fractal is an isometry, i.e. a rotation or a reflection. The questions are motivated by geometric group theory, specifically by the study of the boundaries at infinity of Gromov hyperbolic groups. Since the methods that were used to approach these questions come from complex analysis, I will also present an overview of classical uniformization, as well as more recent packing results for circles and other shapes. Hosts: J.-M. Wu and J. Tyson

Organizational Meeting

Abstract: This meeting is for discussion of topics to be treated in the seminar during the semester. It would be helpful if interested participants bring to the meeting copies of any papers they might propose for sustained focus by the seminar.
