In particular, their monomial expansion is given by a bumpless pipe dream formula. Quantum double Schubert polynomials are polynomial representatives of Schubert classes in the torus-equivariant quantum cohomology of the complete flag variety, but no analogous combinatorial formulation has previously been discovered. In this talk, we will first cover the bumpless pipe dreams formula for double Schubert polynomials. Then we will introduce a generalization of the bumpless pipe dreams called quantum bumpless pipe dreams, giving a combinatorial formula for quantum double Schubert polynomials as a sum of binomial weights of quantum bumpless pipe dreams. Finally, we will give a sketch for the proof of this new formula.", "occurrence_notes":null, "guid":"127734-21859596@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/127734", "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":"Combinatorics Seminar - Department of Mathematics", "group_id":"4885", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/11\/event_127734_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/11\/event_127734_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2024\/11\/event_127734_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2024\/11\/event_127734_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2024\/11\/event_127734_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2024\/11\/event_127734_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/11\/event_127734_original-1.png" }, "occurrence_count":1, "first_occurrence":21859596 } , "129365-21862550": { "datetime_modified":"20241121T134532", "datetime_start":"20241122T150000", "datetime_end":"20241122T170000", "has_end_time":1, "date_start":"2024-11-22", "date_end":"2024-11-22", "time_start":"15:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Search Engines: Search History Zine Launch", "occurrence_title":"", "combined_title":"Search Engines: Search History Zine Launch", "event_subtitle":"", "event_type":"Exhibition", "event_type_id":"7", "description":"RSVP here: https:\/\/forms.gle\/rHPRLFACAWLZSH3m7\r\n\r\nSearch History is a student-led zine publication from the University of Michigan community, hosted by Search Engines: Art, Tech, Justice. Search Engines is funded by the U-M Arts Initiative and the DISCO Network, housed in the Digital Studies Institute. In the last year, Search Engines brought artists such as Astria Suparak, Morehshin Allahyari, and Paul Preciado to the Ann Arbor campus for workshops, performances, and panel discussions. \r\n\r\nThe Search History zine mediates on the implications of an increasingly digital world and asks questions like: How does art help us redefine what technology is? What is your vision of the future and how can art and technology make it a reality? And how do interdisciplinary practices in technology expand traditional knowledge production and storytelling?\r\n\r\nThe Search History Zine Launch will include conversation, food, and reading from zine contributors. Join us on Friday, November 22nd 3PM-5PM ET in North Quad Space 2435 or on Zoom to celebrate the launch of Search History!\r\n\r\nWe want to make our events accessible to all participants. CART services will be provided.
