Using tools from additive combinatorics, Terry and Wolf proved a group theoretic analogue of this result in which finite graphs are replaced by subsets of finite abelian groups. A suitable generalization to arbitrary finite groups was then proved by myself, Pillay, and Terry using model theoretic methods. This talk will focus on an analytic analogue of stability defined for bounded functions on groups. Roughly speaking, the main result of the talk says that if G is amenable, then any stable function on G is almost constant on all translates of a unitary Bohr set in G of bounded complexity. I will also discuss several applications related to Bogolyubobv's Lemma, the Croot-Sisask Lemma, and Folner's Theorem.", "occurrence_notes":null, "guid":"128988-21861980@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/128988", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "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":21861980 } , "133758-21873518": { "datetime_modified":"20250312T112541", "datetime_start":"20250408T160000", "datetime_end":"20250408T170000", "has_end_time":1, "date_start":"2025-04-08", "date_end":"2025-04-08", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EHAP Lecture Series: Alpha Male Replacements in White-Faced Capuchins", "occurrence_title":"", "combined_title":"EHAP Lecture Series: Alpha Male Replacements in White-Faced Capuchins: Meghan Petersdorf, Tulane University", "event_subtitle":"Meghan Petersdorf, Tulane University", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"In primates, male reproductive success is often facilitated by dominance rank. While we have a good understanding of the ultimate benefits that dominance rank provides males, we know less about how male physiology and phenotypes change as males undergo changes in dominance rank. In this seminar, I will discuss our ongoing research on the hormonal, morphological, olfactory, and behavioral correlates of male rank acquisition in white faced-capuchins. Changes in male dominance rank are also associated with high rates of infanticide, which produces extreme sexual conflict. Females have evolved strategies to reduce the occurrence and\/or costs of infanticide to female reproductive success. I will discuss our exploration of one potential female strategy, the Bruce effect - the termination of pregnancy in response to exposure to non-sire males.", "occurrence_notes":null, "guid":"133758-21873518@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/133758", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4448", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Biology","Psychology","Psychology Departmental"], "website":"", "sponsors":[ { "group_name":"Department of Psychology", "group_id":"3615", "website":"http:\/\/www.lsa.umich.edu\/psych\/" }, { "group_name":"Evolution & Human Adaptations Program (EHAP)", "group_id":"4027", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/03\/event_133758_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/03\/event_133758_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21873518 } , "131291-21868120": { "datetime_modified":"20250121T100030", "datetime_start":"20250408T160000", "datetime_end":"20250408T170000", "has_end_time":1, "date_start":"2025-04-08", "date_end":"2025-04-08", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"German Convo on the Go", "occurrence_title":"", "combined_title":"German Convo on the Go", "event_subtitle":"", "event_type":"Social \/ Informal Gathering", "event_type_id":"19", "description":"Members of the U-M community can walk and talk in German with Mary Gell (magell@umich.edu), German language instructor.
