The Hartshorne-Speiser-Lyubeznik number or HSL number of a Noetherian local (or graded) ring is a measure of the nilpotency of Frobenius on local cohomology with support at the (homogeneous) maximal ideal. It is known that the HSL number of such a ring is finite, but it is not known in general how to compute the HSL number for any given ring. In this thesis we present computable upper bounds for the HSL numbers of semigroup rings, toric face rings, and quotients of polynomial rings by monomial ideals, and compute the exact HSL number of monomial hypersurfaces. We also relate the HSL number of a ring to the HSL number of its reduction, provide Macaulay2 code to compute HSL numbers of quotients of polynomial rings, and discuss the application of our results to bounding Frobenius test exponents.", "occurrence_notes":null, "guid":"145996-21898240@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145996", "building_id":"1000206", "building_name":"Angell Hall", "campus_maps_id":"616", "room":"Auditorium B", "location_name":"Angell Hall", "has_livestream":1, "livestream_type":"zoom", "livetream_require_login":0, "livestream_id":"98025127294", "livestream_link":"https:\/\/umich.zoom.us\/j\/98025127294", "cost":"", "tags":["Mathematics","Graduate Students","Graduate","Dissertation"], "website":"", "sponsors":[ { "group_name":"Dissertation Defense - Department of Mathematics", "group_id":"4889", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/02\/event_145996_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/02\/event_145996_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21898240 } , "144742-21895800": { "datetime_modified":"20260212T131626", "datetime_start":"20260312T140000", "datetime_end":"20260312T153000", "has_end_time":1, "date_start":"2026-03-12", "date_end":"2026-03-12", "time_start":"14:00:00", "time_end":"15:30:00", "time_zone":"America\/Detroit", "event_title":"Classroom Activities for Engaging with Politics, Policy, & Social Issues", "occurrence_title":"", "combined_title":"Classroom Activities for Engaging with Politics, Policy, & Social Issues: From Ginsberg Center and Center for Research on Learning & Teaching (CRLT)", "event_subtitle":"From Ginsberg Center and Center for Research on Learning & Teaching (CRLT)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Across the disciplines, we can help our students to build skills for civic and democratic engagement that will serve them throughout their careers and lives.

biological barriers, physicochemical properties of drug molecules, formulation and transport in vivo. Designing molecular structures that persist at the administration site or that promote drainage to regional lymphatic networks may enhance immune responses while sparing immune-related adverse events. Here, drug transport and local elimination mechanisms will be overviewed. Then, examples of molecular designs to direct drug delivery will be presented. Autoimmune therapies were designed by our lab to promote the drainage of autoantigens to secondary lymphoid organs to treat autoimmune diseases. Specifically, the size and solubility of these molecular constructs were tuned to promote access to the lymphatic compartment and induce immune tolerance in mouse models of type 1 diabetes. Our lab has also recently explored the design of immunostimulants that persist in tumor tissue after intratumoral\/perilesional injection. Intratumoral immunotherapy is proposed to work synergistically with checkpoint inhibitors making a nonresponsive \u2018cold\u2019 tumor \u2018hot\u2019 by recruiting and activating tumor infiltrating lymphocytes. This approach can suffer from systemic immune-related adverse reactions, however, if enough immunostimulant escapes the site of administration. Data on the use of electrostatic mechanisms to promote tumor retention will be presented. These examples underscore the need for rational design of drug molecules or formulations based upon the route of delivery and biological barriers encountered. \n\nBio:\nCory Berkland is the Mark and Becky Levin Professor in the Departments of Biomedical Engineering and Chemistry at Washington University in Saint Louis.
