Ruprecht-Karls-Universität Heidelberg Mathematisches Institut Prof. Dr. Anna Wienhard Prof. Dr. Peter Albers Heidelberg, 02.05.2019 Differential Geometry Seminar "Fundamental domains in the complex hyperbolic plane and its boundary at infinity " Dr. Miguel Acosta, Universität Luxemburg Abstract: In this talk, we will describe some fundamental domains for subgroups of PU(2,1) in the complex hyperbolic plane and in its boundary at infinity, and we will focus on the examples constructed by Parker-Will and Deraux-Falbel. We will recall some geometric properties of the complex hyperbolic plane, as well as the hypersurfaces called bisectors. The fundamental domains that we consider can be used for proving the discreteness of some groups, and provide geometric structures on manifolds. Donnerstag, den 09.
