Topology Seminar (Main Talk): Geometric finiteness in Hadamard manifolds

Seminar | October 24 | 4-5 p.m. | 3 Evans Hall

 Beibei Liu, UC Davis

 Department of Mathematics

In this talk, we focus on negatively pinched Hadamard manifolds which are complete, simply connected Riemannian manifolds with sectional curvature ranging between two negative constants. We use the techniques in geometric groups theory to generalize Bishop’s characterization of geometric finiteness to discrete isometry subgroups of negatively pinched Hadamard manifolds.
