While the completion of a regular local ring is always a regular local ring, Nagata gave an example of a normal local ring with non-reduced completion. As Heitmann showed, there are even unique factorization domains with this property. These rings are quite hard to describe, however, and for good reason! Essentially any local ring that one can write down will be **excellent**, meaning that properties like reducedness and normality are shared by the ring and its completion. We discuss a set of highly non-constructive techniques, developed my Heitmann and others, to study the fine details of the relationship between a ring and its completion, allowing us to answer questions such as ``which rings are the completion of an integral domain?'' Lastly, we mention a conjectural application of these techniques to the deformation of perfectoid purity in Gorenstein rings.", "occurrence_notes":null, "guid":"141165-21888274@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141165", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"3088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Student Commutative Algebra Seminar - Department of Mathematics", "group_id":"4908", "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":21888274 } , "140329-21886930": { "datetime_modified":"20251013T172559", "datetime_start":"20251028T160000", "datetime_end":"20251028T180000", "has_end_time":1, "date_start":"2025-10-28", "date_end":"2025-10-28", "time_start":"16:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"2025 David Noel Freedman Lecture", "occurrence_title":"", "combined_title":"2025 David Noel Freedman Lecture: Magic, Curses, and the Letters of Paul: Seeking Justice with Laura Nasrallah", "event_subtitle":"Magic, Curses, and the Letters of Paul: Seeking Justice with Laura Nasrallah", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Please join us for the 2025 David Noel Freedman Lecture with Laura Nasrallah from Yale University, Department of Religious Studies; Divinity School\r\n\r\nSome translate it \u201cjustification,\u201d some \u201crighteousness.\u201d The Greek word dikaiosyn\u0113, found often in the letters of Paul, can also be understood in terms of justice.

Since RNA function depends on its 3D structure and conformational changes, research in this area focuses on the study of RNA structure along with its folding stability, kinetics, and interactions with metal ions and other molecules. Key questions include: How can the native fold be predicted from the sequence? For a given RNA target, how can RNA-small molecule interactions be predicted and potential drug candidates identified? Developing computational tools to address these questions remains challenging due to limited RNA structural and binding data. To predict 3D structure from sequence, we developed the Vfold pipeline by integrating statistical analysis of RNA structures and molecular dynamics simulations. The Vfold approach showed highly promising results at the international CASP16 competition for biomolecular structure predictions. To design RNA-targeted drugs, we developed the RLDOCK and SPRank pipelines for physics-based and data-driven predictions of ligand-RNA interactions. These models may become useful tools for understanding the structure-based mechanism of RNA function and for accelerating RNA-targeted therapeutic discovery.", "occurrence_notes":null, "guid":"138419-21882923@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/138419", "building_id":"1000158", "building_name":"Chemistry Dow Lab", "campus_maps_id":"34", "room":"1640", "location_name":"Chemistry Dow Lab", "has_livestream":0, "cost":"", "tags":["Chemistry","Science","Chemical Biology"], "website":"https:\/\/physics.missouri.edu\/people\/chen", "sponsors":[ { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" }, { "group_name":"LSA Biophysics", "group_id":"3767", "website":"" }, { "group_name":"Chemical Biology", "group_id":"4385", "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":21882923 } , "140887-21887771": { "datetime_modified":"20251020T083040", "datetime_start":"20251028T160000", "datetime_end":"20251028T170000", "has_end_time":1, "date_start":"2025-10-28", "date_end":"2025-10-28", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"CM-AMO Seminar | Physics at the Intersection of AMO and Plasmas", "occurrence_title":"", "combined_title":"CM-AMO Seminar | Physics at the Intersection of AMO and Plasmas: Scott Baalrud (U-M Nuclear Engineering and Radiological Sciences)", "event_subtitle":"Scott Baalrud (U-M Nuclear Engineering and Radiological Sciences)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Two assumptions at the heart of standard plasma theory are that the plasma is weakly coupled in the sense that the potential energy of Coulomb interactions is weak compared to the kinetic energy, and that the plasma is weakly magnetized in the sense that the gyroradii of particles are large compared to the Debye length. A focus of my research group is to extend plasma kinetic theories to treat conditions of strong Coulomb coupling, strong magnetization, or both. The work is largely motivated by topics in dense plasmas, like inertial confinement fusion or dense astrophysical objects like white dwarfs or stellar interiors. However, conditions of strong coupling and\/or strong magnetization can also be created using table-top scale experiments developed in the AMO field. These have the advantage of a controlled and well-diagnosed platform to test the models. In this talk I will describe two categories of experiments (conducted by others) that we have used to validate our theories. The first is ultracold neutral plasmas. These are plasmas created in cold-atom traps (MOTs), where a plasma is produced by laser ionization and diagnosed using laser-induced fluorescence. These experiments produce strongly coupled plasmas in a charge-neutral state. The second is non-neutral plasmas confined in Penning traps. These are strongly magnetized plasmas that can range from weak to strong coupling. The past work has been productive, but there is much more that could be done through collaboration between AMO and plasma physicists.\r\n\r\nBio:\r\nScott Baalrud is a Professor in Nuclear Engineering and Radiological Sciences at the University of Michigan.
