Plabic Graphs are finer combinatorial objects than Grassmann necklaces that not only index positroids but also parametrize points in positroids, through the boundary measurement map. Given a reduced plabic graph, we can assign target face labels to each face, and the boundary face labels give us the corresponding Grassmann necklace, which tells us the non-vanishing pluckers in the positroid. It is known that the face label pluckers give a cluster in the cluster structure on the Grassmannian. A natural question is, what can the internal face labels tell us geometrically? It is not generally true that these are the non-vanishing pluckers in the image of the boundary measurement map for positroids over the complex numbers. In this talk, we introduce the twist map, constructed by Muller-Speyer, which are automorphisms of the positroid variety, taking the image of the boundary measurement map to a torus defined by the non-vanishing of face label pluckers.", "occurrence_notes":null, "guid":"134954-21875726@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134954", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"3866", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Student Combinatorics Seminar - Department of Mathematics", "group_id":"4907", "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":21875726 } , "125915-21856282": { "datetime_modified":"20241118T120053", "datetime_start":"20250414T160000", "datetime_end":"20250414T170000", "has_end_time":1, "date_start":"2025-04-14", "date_end":"2025-04-14", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Totally real points in the Mandelbrot set", "occurrence_title":"", "combined_title":"Totally real points in the Mandelbrot set: Sarah Koch, U(M)", "event_subtitle":"Sarah Koch, U(M)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":":)", "occurrence_notes":null, "guid":"125915-21856282@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/125915", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"3096", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Complex Analysis, Dynamics and Geometry Seminar - Department of Mathematics", "group_id":"4887", "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":21856282 } , "133254-21872655": { "datetime_modified":"20250307T131831", "datetime_start":"20250414T163000", "datetime_end":"20250414T173000", "has_end_time":1, "date_start":"2025-04-14", "date_end":"2025-04-14", "time_start":"16:30:00", "time_end":"17:30:00", "time_zone":"America\/Detroit", "event_title":"Knight-Hennessy Scholars Info Session: Graduate Scholarships at Stanford", "occurrence_title":"", "combined_title":"Knight-Hennessy Scholars Info Session: Graduate Scholarships at Stanford: Christian Tanja, KHS Senior Assistant Director of Admissions", "event_subtitle":"Christian Tanja, KHS Senior Assistant Director of Admissions", "event_type":"Presentation", "event_type_id":"16", "description":"Join ONSF and Assistant Director of Admissions at the Knight-Hennessy Scholars Program, Christian Tanja, for an information session.

The trio, which also features the world class French improvising cellist, Vince Curt, performs original music that crosses the boundaries of jazz and classical music inspired by the early 20th century French composers Ravel, Faure, Poulenc, Milhaud, and the lesser known female composers, Germaine Tailleferre and Lili Boulanger. The band has toured throughout the USA and Europe over the past 8 years to rave reviews from audiences and critics alike including performances at festivals, clubs, theaters, universities, churches, chamber music series, and performing arts centers.\n\nABOUT THE GUEST ARTISTS\n\nReverso\u2019s repertoire features original compositions by all three members of the ensemble inspired by the music of Lili Boulanger, Faure, Milhaud, Poulenc, Honeggar, Tailleferre, and Ravel\u2019s \u201cLe Tombeau de Couperin\u201d.\n\nRYAN KEBERLE is one of New York\u2019s busiest trombonists. He leads his own big band, the All Ears Orchestra, along with the innovative small ensembles Catharsis, Reverso and Collectiv Do Brasil. He is a featured soloist with the Maria Schneider Orchestra and Darcy James Argue\u2019s Secret Society. Keberle is the Director of Jazz and Brass Studies at CUNY\u2019s Hunter College and teaches the jazz trombone studio at the Manhattan School of Music.\n \nFRANK WEST resides in Burgundy, France, where he splits his activities between pianist, producer, composer, and arranger. Several of his albums have been awarded the French \u201cVictoires du Jazz\u201d, and he has won grants from the French-American Jazz Exchange. He is the music director for acclaimed French-Lebanese trumpeter, Ibrahim Maalouf. He has also worked with Dave Douglas, Mark Turner, Larry Grenadier, Clarence Penn, and Gretchen Parlato.\n \nVINCE CURT is one of France\u2019s finest cellists and improvising musicians. He has collaborated with several of France\u2019s most important jazz musicians, including Michel Petrucciani, Martial Solal, Louis Sclavis, Marc Ducret, Dominique Pifar\u00e9ly, and Yves Robert.\n\n*Supported by Jazz & New Music, a program of Villa Albertine and Albertine Foundation.*", "occurrence_notes":null, "guid":"134691-21874718@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134691", "building_id":"1000440", "building_name":"Earl V.
