Just as complex-analytic spaces provide a robust framework for analytic geometry over C, rigid-analytic spaces offer a natural setting for analytic geometry over Q_p.

Within this program, the relative Langlands program has emerged as one of its most important and productive branches. In this talk, I will … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250227T160000-amie-wilkinson@math.utah.edu DTSTART;TZID=America/Denver:20250227T160000 DTEND;TZID=America/Denver:20250227T170000 DTSTAMP:20260922T150858Z SUMMARY:Dynamical Symmetry DESCRIPTION:Speaker: Amie Wilkinson\, University of Chicago\n\nThe centralizer $Z(f)$ of a diffeomorphism $f: M \to M$ of a closed manifold $M$ is the group of all diffeomorphisms commuting with $f$; it is the collection of dynamical symmetries of $f$. The centralizer of $f$ always contains the group $\langle f \rangle$ generated by $f$ as a normal subgroup, … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250306T160000-mark-iwen@math.utah.edu DTSTART;TZID=America/Denver:20250306T160000 DTEND;TZID=America/Denver:20250306T170000 DTSTAMP:20260922T150858Z SUMMARY:Low-Distortion Embeddings of Submanifolds of $R^n$: Lower Bounds, Faster Realizations, and Terminal Embeddings DESCRIPTION:Speaker: Mark Iwen\, Michigan State University\n\nLet $M$ be a smooth submanifold of $\mathbb{R}^n$ equipped with the Euclidean (chordal) metric. This talk will consider the smallest dimension, $m$, for which there exists a bi-Lipschitz function $f:M \to \mathbb{R}^m$ with bi-Lipschitz constants close to one. We will begin by presenting a bound for … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250320T160000-jesse-wolfson@math.utah.edu DTSTART;TZID=America/Denver:20250320T160000 DTEND;TZID=America/Denver:20250320T170000 DTSTAMP:20260922T150858Z SUMMARY:Hodge theory and resolvent problems DESCRIPTION:Speaker: Jesse Wolfson\, UC Irvine\n\nHow hard is it to solve a degree 7 polynomial? How complicated is a branched cover, an algebraic group, a local system? Resolvent problems, e.g. Hilbert's 13th problem, form a rich and challenging framework for asking these questions, and one that both invites and resists ideas and methods from … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250325T160000-julia-pevtsova@math.utah.edu DTSTART;TZID=America/Denver:20250325T160000 DTEND;TZID=America/Denver:20250325T170000 DTSTAMP:20260922T150858Z SUMMARY:Support theories and tensor triangular geometry in pictures DESCRIPTION:Speaker: Julia Pevtsova\, University of Washington, Seattle\n\nTensor triangular geometry associates a rich geometric structure, the spectrum, to a “nice” category where one can add, subtract and multiply objects. Examples include modules over a commutative ring and representations of a finite group. I’ll give an introduction to tensor triangular geometry via … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250327T160000-dejan-slepcev@math.utah.edu DTSTART;TZID=America/Denver:20250327T160000 DTEND;TZID=America/Denver:20250327T170000 DTSTAMP:20260922T150858Z SUMMARY:Gradient flows for sampling and their deterministic interacting particle approximations DESCRIPTION:Speaker: Dejan Slepcev\, Carnegie Mellon University\n\nMotivated by the task of sampling measures in high dimensions we will discuss a several gradient flows in the spaces of measures, including the Wasserstein gradient flows of Maximum Mean Discrepancy and relative entropy, the Stein Variational Gradient Descent and a new Radon-Wasserstein gradient … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250403T160000-mauro-maggioni@math.utah.edu DTSTART;TZID=America/Denver:20250403T160000 DTEND;TZID=America/Denver:20250403T170000 DTSTAMP:20260922T150858Z SUMMARY:On two problems in machine learning for dynamical systems: learning interaction laws in particle systems, and digital twins in cardiac electrophysiology DESCRIPTION:Speaker: Mauro Maggioni\, Johns Hopkins University\n\nI will discuss recent results in two research directions at the intersection of statistical learning and modeling of dynamical systems. First, we consider systems of interacting agents or particles, which are commonly used in models throughout the sciences, and can exhibit complex, emergent … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250408T160000-claudia-miller@math.utah.edu DTSTART;TZID=America/Denver:20250408T160000 DTEND;TZID=America/Denver:20250408T170000 DTSTAMP:20260922T150858Z SUMMARY:Differentials and differential operators DESCRIPTION:Speaker: Claudia Miller\, Syracuse University\n\nIn the first part, I will describe Kähler differentials and derivations and some of the history behind the classic Lipman-Zariski Conjecture, as well as a generalized question proposed by Graf. Together with Vassiliadou, we give a partial answer to Graf’s question for a certain class of varieties. … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-spring/ END:VEVENT BEGIN:VEVENT UID:20250410T160000-ben-antieau@math.utah.edu DTSTART;TZID=America/Denver:20250410T160000 DTEND;TZID=America/Denver:20250410T170000 DTSTAMP:20260922T150858Z SUMMARY:K-groups and machine computation DESCRIPTION:Speaker: Ben Antieau\, Northwestern University\n\nI will describe the results of joint work with Achim Krause and Thomas Nikolaus on a computer algorithm to compute the algebraic K-groups of simple rings like $\mathbb{Z}/4$ or $\mathbb{Z}/9$.
