Among the main results are the determination of the spectrum of the (non-selfadjoint) linearized operator, uncovering a remarkable L^2 growth phenomenon related to zero-energy resonance, and a complete construction of the distorted Fourier transform at small energies. The latter hinges upon a meticulous analysis of the behavior of the resolvent in the upper and lower half-planes in a small disk around zero-energy.", "occurrence_notes":null, "guid":"131283-21868067@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/131283", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics","Applied Mathematics"], "website":"", "sponsors":[ { "group_name":"Differential Equations Seminar - Department of Mathematics", "group_id":"4888", "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":21868067 } , "134458-21874375": { "datetime_modified":"20250402T103840", "datetime_start":"20250403T160000", "datetime_end":"20250403T170000", "has_end_time":1, "date_start":"2025-04-03", "date_end":"2025-04-03", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Thursday Seminar Series - There and back again: Philopatry, global change, and the evolution of seasonal migration", "occurrence_title":"", "combined_title":"EEB Thursday Seminar Series - There and back again: Philopatry, global change, and the evolution of seasonal migration: Ben Winger, University of Michigan", "event_subtitle":"Ben Winger, University of Michigan", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Seminar summary: Bird migration is one of our world\u2019s most celebrated natural wonders. But how and why has migration evolved, and what influence does it have on the ecology and evolution of migratory species? Ben will discuss research that his lab has been conducting on the evolutionary dynamics of bird migration. This work highlights seasonal migration as an adaptive strategy for site fidelity, challenging traditional views of migration as a dispersal strategy for exploring new territories. The work further reveals migratory distance as a fundamental axis of the slow-fast continuum of life history that predicts the balance of survival and reproduction, and leads to enhanced demographic stability and genetic diversity over evolutionary timescales.", "occurrence_notes":null, "guid":"134458-21874375@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134458", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["Bsbsigns","evolutionary biology","Free","Museum - Herbarium","Museum - Zoology","Museum Of Zoology","biological science","Ecology & Biology","department of ecology and evolutionary biology","Discussion","Ecology And Evolutionary Biology","eeb"], "website":"", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/03\/event_134458_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/03\/event_134458_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21874375 } , "122465-21849233": { "datetime_modified":"20250106T123728", "datetime_start":"20250403T160000", "datetime_end":"20250403T180000", "has_end_time":1, "date_start":"2025-04-03", "date_end":"2025-04-03", "time_start":"16:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"EIHS Lecture: Foreigners in Their Own Land: Chernobyl under the Russian Occupation (2022)", "occurrence_title":"", "combined_title":"EIHS Lecture: Foreigners in Their Own Land: Chernobyl under the Russian Occupation (2022): Serhii Plokhii (Harvard University)", "event_subtitle":"Serhii Plokhii (Harvard University)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"On February 24, 2022, the first day of Russia\u2019s all-out attack on Ukraine, armored vehicles approached the Chernobyl nuclear power plant in northern Ukraine. Russian occupation of the plant, which would last thirty-five days, had begun. Only the dedication and resolve of Ukrainian personnel, who were held hostage and worked shifts for weeks instead of days, spared the world a new Chernobyl accident. Meanwhile, a much more dangerous situation developed at the Zaporizhia nuclear power plant in southern Ukraine, the largest such facility in Europe. Following an attack there in March 2022, the Russian military remains in control. In this lecture Serhii Plokhii discusses the challenges that the Russian takeover of the nuclear sites presents to the world. We must face up to a new reality: there has already been warfare at two nuclear sites, and others are vulnerable. The lecture is based on Plokhii\u2019s most recent book, \"Chernobyl Roulette\" (2024).\r\n\r\nSerhii Plokhii (Plokhy) is the Mykhailo Hrushevsky Professor of Ukrainian History and the director of the Ukrainian Research Institute at Harvard University. A leading authority on Ukraine, Russia, and Eastern Europe, he has published extensively on the international history of World War II and the Cold War. His books won numerous awards, including the Lionel Gelber Prize for the best English-language book on international relations and the Baillie Gifford Prize for Non-Fiction (UK). His latest book, \"Chernobyl Roulette: War in the Nuclear Disaster Zone\" was released by W.W. Norton in US and Penguin in UK in September May 2024.\r\n\r\nThis event presented by the Eisenberg Institute for Historical Studies.
