The spectral theory of soliton gases is concerned about macroscopic characteristics of large soliton ensembles. We go briefly over the history of the subject, such as V. Zakharov\u2019s (1971) expression of the average velocity of a trial soliton in a (diluted) gas and the idea of the thermodynamic limit of wavenumbers and frequencies of finite gap solutions of G. El (2003). We then discuss some recent results and open problems, as well as some methods of potential theory and algebraic geometry that appear to be relevant for soliton gases.\n\nContact: Peter Miller", "occurrence_notes":null, "guid":"148877-21905039@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148877", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1084", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics","Applied Mathematics"], "website":"", "sponsors":[ { "group_name":"Applied Interdisciplinary Mathematics (AIM) Seminar - Department of Mathematics", "group_id":"4882", "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":21905039 } , "149753-21907057": { "datetime_modified":"20260916T151809", "datetime_start":"20261009T150000", "datetime_end":"20261009T160000", "has_end_time":1, "date_start":"2026-10-09", "date_end":"2026-10-09", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Chow Vanishing and Motives of Cluster Varieties", "occurrence_title":"", "combined_title":"Chow Vanishing and Motives of Cluster Varieties: Josie Hlavinka (UC Berkeley)", "event_subtitle":"Josie Hlavinka (UC Berkeley)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Progress over the last decade has shown that the cohomologies of full rank, locally acyclic cluster varieties enjoy remarkable combinatorial structures.
