Given a single noncompact finite-volume hyperbolic 3-manifold M, the theorem provides a construction for a countably infinite family of closed hyperbolic 3-manifolds converging to M in a geometric sense. The theorem is a major source of examples of 3-manifolds admitting hyperbolic structures, and closely connects the topology of a 3-manifold to the analysis of the character variety of its fundamental group in PSL(2, C). In this talk, we discuss some analogs and generalizations of Thurston's theorem in the context of general (arbitrary-rank) semisimple Lie groups. We will explain how our results provide a way to construct new examples of Anosov and relatively Anosov representations into higher-rank Lie groups; we will also discuss upcoming joint work with Jeff Danciger, which applies our results to construct exotic new examples of convex cocompact and geometrically finite groups acting on complex hyperbolic 3-space.", "occurrence_notes":null, "guid":"130738-21866609@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/130738", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"3866", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"RTG Seminar on Geometry, Dynamics and Topology - Department of Mathematics", "group_id":"4900", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21866609 } , "131053-21867657": { "datetime_modified":"20250113T112027", "datetime_start":"20250115T160000", "datetime_end":"20250115T170000", "has_end_time":1, "date_start":"2025-01-15", "date_end":"2025-01-15", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Student AIM Seminar: Planning Meeting", "occurrence_title":"", "combined_title":"Student AIM Seminar: Planning Meeting", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Welcome to the new semester!
