While traditionally studied in the divisor and curves cases, cones of cycles of intermediate dimension have recently been the subject of much study. We discuss some results on nef and effective cones of intermediate dimension cycles in the case of Hilbert schemes of points. In particular, we look at the Hilbert scheme of 3 points in $\\mathbb{P}^3$. Our computation generalizes results of Ryan & Stathis and requires a careful analysis of the PGL orbits in the Hilbert scheme, as well as a new basis of the Chow ring inspired by Mallavibarrena and Sols.", "occurrence_notes":null, "guid":"151651-21911898@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/151651", "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":"Algebraic Geometry Seminar - Department of Mathematics", "group_id":"4880", "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":21911898 } , "149378-21906293": { "datetime_modified":"20260908T115944", "datetime_start":"20260916T160000", "datetime_end":"20260916T180000", "has_end_time":1, "date_start":"2026-09-16", "date_end":"2026-09-16", "time_start":"16:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"Democracy Against Workers?", "occurrence_title":"", "combined_title":"Democracy Against Workers?: Noam Lupu (Vanderbilt University), Nicholas Carnes (Duke University), Adam Dean (George Washington University)", "event_subtitle":"Noam Lupu (Vanderbilt University), Nicholas Carnes (Duke University), Adam Dean (George Washington University)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Webinar Link: https:\/\/myumi.ch\/ww7q9\n\nCanonical models of democracy expect working-class people to be the main beneficiaries -- even the natural beneficiaries -- of democratization. Yet not all democratic systems deliver economic gains to average citizens. Even after they gain the right to vote, very rarely do they become candidates for office and get to serve as the people's representatives. When is \"democracy against workers\" and how might we make it work better for working people? In this Democracy Week roundtable, Nick Carnes, Adam Dean, and Noam Lupu discuss their book projects on these themes, with Ann Heffernan serving as respondent.\n\nIf there is anything we can do to make this event accessible to you, please contact us at emergingdemocracies@umich.edu.
