This theorem has profound extensions to higher dimensions, including Thurston\u2019s geometrization program and, notably, the resolution of the Poincar\u00e9 conjecture. It is no wonder that this theorem is one of the most important theorems, if not the most important theorem, in the last 150 years.\r\n\r\nHowever, its rich history and far-reaching impacts are often underappreciated. For example, the initial formulations and attempted proofs by Klein and Poincar\u00e9 using the method of continuity introduced many original ideas that have not been fully explored. Later, Teichm\u00fcller\u2019s innovative use of the method of continuity played a crucial role in his revolutionary work on Teichm\u00fcller space, profoundly influencing the study of moduli spaces of Riemann surfaces. Yet, this deep historical and conceptual connection is frequently overlooked.\r\n\r\nIn this talk, I will trace the historical development of the uniformization theorem, from its early formulations to its lasting influence across mathematics. I will explore its connections to seemingly unrelated results and modern mathematical areas, particularly in Teichm\u00fcller theory and moduli spaces. Through this exploration, I aim to shed light on the theorem\u2019s profound influence, inspire new perspectives on its unifying role in contemporary mathematics.", "occurrence_notes":null, "guid":"139670-21885878@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/139670", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"https:\/\/lsa.umich.edu\/math\/people\/faculty\/lji.html", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/09\/event_139670_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/09\/event_139670_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21885878 } , "138671-21883564": { "datetime_modified":"20260311T094357", "datetime_start":"20251007T160000", "datetime_end":"20251007T173000", "has_end_time":1, "date_start":"2025-10-07", "date_end":"2025-10-07", "time_start":"16:00:00", "time_end":"17:30:00", "time_zone":"America\/Detroit", "event_title":"First Year Success Seminar Series", "occurrence_title":"", "combined_title":"First Year Success Seminar Series: More W26 seminars are on the way!
