SUMMARY:Workshop / Seminar:Student Commutative Algebra Seminar: Local Rings with a Prescribed Completion
DESCRIPTION:The relationship between a Noetherian local ring (R\, m) and its m-adic completion can be surprisingly pathological. 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.

SUMMARY:Lecture / Discussion:2025 David Noel Freedman Lecture
DESCRIPTION:Please join us for the 2025 David Noel Freedman Lecture with Laura Nasrallah from Yale University\, Department of Religious Studies\; Divinity School\n\nSome translate it “justification\,” some “righteousness.” The Greek word dikaiosynē\, found often in the letters of Paul\, can also be understood in terms of justice. This lecture explores ideas of justice in the ancient world\, focusing on acts of “magic”: on curses carved into lead and on curses within Paul’s letters. From Mediterranean antiquity and the letters of Paul\, we move to larger questions about ritual and practice\, about definitions of magic and of scripture\, and about how people seek justice\, whether in Mediterranean antiquity or in our own times.\n\nMichigan League\, Henderson Room\, 3rd Floor\nTuesday\, October 28th\, 4 - 6pm\n\nRegistration is requested but not required- https://myumi.ch/Mkmj6\nLight refreshments will be served.

SUMMARY:Workshop / Seminar:Advancing RNA Structural Biology and Therapeutics: Integrating Physical and Data-Driven Computational Approaches
DESCRIPTION:Emerging biomedical advances from precision medicine to synthetic biology highlight RNA's central role as both a regulator and an information carrier. 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.

SUMMARY:Workshop / Seminar:CM-AMO Seminar | Physics at the Intersection of AMO and Plasmas
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.\n\nBio:\nScott Baalrud is a Professor in Nuclear Engineering and Radiological Sciences at the University of Michigan. Prior to arriving in Ann Arbor in January 2021\, he was on the faculty of the Physics and Astronomy Department at the University of Iowa (2013-2020)\, a Feynman postdoc at Los Alamos National Laboratory (2012-2013)\, and a DOE postdoc at the University of New Hampshire (2010-2012). All three of his academic degrees are from the University of Wisconsin-Madison (PhD 2010\, MS 2008\, BS 2006). His research accomplishments have been acknowledged by the American Physical Society Thomas Stix Award\, the Institute of Physics Hershkowitz Early Career Award\, and early career awards from NSF\, DOE and AFOSR.

SUMMARY:Lecture / Discussion:Colloquium: Anthony Licata- Geometric Group Theory and Triangulated Categories
DESCRIPTION:Abstract: There are tantalising analogies between the theory of mapping class groups and other classes of groups\, and as a result the well-developed study of mapping class groups has been an important model to mimic in other parts of group theory.  I'll try to describe how some ideas from geometric group theory have been imported into the study of groups arising in homological algebra and representation theory.\n\nBio: I grew up in Texas\, and got my PhD from Yale in 2007.  I have worked at the Australian National University since 2012. I am a Professor in the Mathematical Sciences Institute at the Australian National University in Canberra\, Australia.\n\nI work on geometric representation theory and categorification.  Most of my work involves interactions between representation theory and low-dimensional topology (braids\, knot homologies)\, symplectic algebraic geometry (quiver varieties\, Hilbert schemes)\, and algebraic combinatorics (symmetric functions\, hyperplane arrangements).

SUMMARY:Lecture / Discussion:Emerging Democracies Roundtable | A New Era of War and Dictators?
DESCRIPTION:After the Cold War ended\, democracy seemed to become the predominant form of government and civil war seemed to become the predominant form of warfare worldwide. Now\, international warfare and authoritarian regimes seem to be making major simultaneous comebacks. This roundtable considers whether these comebacks are real or illusory\, and if the relationships between types of political regimes and types of political violence are truly shifting.\n   \nWebinar link: https://myumi.ch/R3ryd\n\n*Cosponsored by Conflict & Peace\, Research & Development (CPRD)*.\n\nIf there is anything we can do to make this event accessible to you\, please contact us at rrazmi@umich.edu. Please be aware that advance notice is necessary as some accommodations may require more time for the university to arrange.
