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.

But this does not need to happen in discrete time. This suggests defining a new object, the specific relative entropy, as a scaled limit of the relative entropy between the discretized laws of the martingales. This definition goes all the way back to Nina Gantert's PhD thesis, and in recent time Hans Foellmer has rekindled the study of this object by for instance obtaining a novel transport-information inequality.\r\n\r\nIn this talk I will first discuss the existence of a closed formula for the specific relative entropy, depending on the quadratic variation of the involved martingales. Next I will describe an application of this object to prediction markets. Concretely, David Aldous asked in an open question to determine the 'most exciting game', i.e. the prediction market with the highest entropy. With M. Beiglbock we give a concise answer to this question. Finally, if time permits, I will give a glimpse to different extensions of this object, e.g. to higher dimensions or when we replace the role of the relative entropy by a power of the Wasserstein distance, as recently developed with X.
