In the past few years, a general theory of stability, $\\Theta$-stratifications, and good moduli spaces for algebraic stacks has generalized many aspects of this moduli problem. However, questions of boundedness do not yet have a general answer -- this tends to be one of the trickiest parts of applying the machinery. I will discuss a new approach to boundedness for a vast generalization of the moduli of vector bundles on a curve: moduli spaces of objects in a dg-category that are semistable with respect to a Bridgeland stability condition. This involves reformulating the notion of a Bridgeland stability condition in a way that is especially convenient for moduli theory.", "occurrence_notes":null, "guid":"129932-21864898@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/129932", "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":"Algebraic Geometry Seminar - Department of Mathematics", "group_id":"4880", "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":21864898 } , "133092-21872377": { "datetime_modified":"20250303T063233", "datetime_start":"20250226T153000", "datetime_end":"20250226T161500", "has_end_time":1, "date_start":"2025-02-26", "date_end":"2025-02-26", "time_start":"15:30:00", "time_end":"16:15:00", "time_zone":"America\/Detroit", "event_title":"Pathways Into Teaching - The Marshall Teacher Residency", "occurrence_title":"", "combined_title":"Pathways Into Teaching - The Marshall Teacher Residency", "event_subtitle":"", "event_type":"Careers \/ Jobs", "event_type_id":"2", "description":"The Pathways Into Teaching workshop is an overview of the various pathways into teaching, including Master's programs, Intern Programs and Teacher Residencies.
