Hauptseminar Geometrie

This talk will describe various examples of surface groups in SO(4,1) in terms of fundamental domain of its action on S^3. This includes the first examples by Gromov-Lawson-Thurston, and new examples. We will also look at the quotient 3 manifolds which are circle bundles over closed surfaces and a proof of a soft bound on the Euler number of such circle bundles.
