This talk describes recent progress in using the geometry of elliptic fibrations through the approach known as F-theory to better understand the physics of a broad class of nonperturbative string compactifications, to identify ways in which the Standard Model of particle physics arises naturally in this context, and to shed light on the structure of the largest known set of Calabi-Yau manifolds. In particular, the talk will describe a recent complete analysis the full set of 470 million toric hypersurface Calabi-Yau threefolds, of which over 99.99% have an elliptic or genus one fiber structure. This approach also helps understand the way in which all of these Calabi-Yaus are connected, and provides strong evidence that the set of such manifolds is finite. This talk describes recent work with Shing Yan Li and with Fatima Abbasi and Richard Nally, and upcoming work with Lara Anderson, James Gray, and Richard Nally.", "occurrence_notes":null, "guid":"141764-21889330@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141764", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["High Energy Theory Seminar","Physics","Science"], "website":"", "sponsors":[ { "group_name":"Leinweber Institute for Theoretical Physics", "group_id":"4286", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" }, { "group_name":"Leinweber Institute for Theoretical Physics Seminars", "group_id":"4311", "website":"" }, { "group_name":"Leinweber Institute for Theoretical Physics High Energy Theory Seminars", "group_id":"4313", "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":21889330 } , "137710-21880612": { "datetime_modified":"20251118T164939", "datetime_start":"20251121T150000", "datetime_end":"20251121T160000", "has_end_time":1, "date_start":"2025-11-21", "date_end":"2025-11-21", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"No Combinatorics seminar", "occurrence_title":"", "combined_title":"No Combinatorics seminar: Cancelled", "event_subtitle":"Cancelled", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Cancelled", "occurrence_notes":null, "guid":"137710-21880612@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/137710", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4096", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Combinatorics Seminar - Department of Mathematics", "group_id":"4885", "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":21880612 } , "141630-21889114": { "datetime_modified":"20251121T134548", "datetime_start":"20251121T150000", "datetime_end":"20251122T030000", "has_end_time":1, "date_start":"2025-11-21", "date_end":"2025-11-22", "time_start":"15:00:00", "time_end":"03:00:00", "time_zone":"America\/Detroit", "event_title":"Nov 21 @ 3pm-3am DROP-IN -- Roblox Gaming Session -- GG Brown 2505", "occurrence_title":"", "combined_title":"Nov 21 @ 3pm-3am DROP-IN -- Roblox Gaming Session -- GG Brown 2505: Play Games [Roblox at UM] Free food provided!", "event_subtitle":"Play Games [Roblox at UM] Free food provided!", "event_type":"Social \/ Informal Gathering", "event_type_id":"19", "description":"Meet new people through our Roblox Gaming Session, followed by a friendly Game Jam for those interested.\r\n\r\nWe will be playing a variety of games and official Roblox Merch will be present!\r\n\r\nFree food Provided - Register even if you won't be on time!
