For higher-dimensional varieties, the moduli theory of those with negative curvature has been studied for several decades and known to link to the minimal model program. However, constructing … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20250910T160000-berton-earnshaw@math.utah.edu DTSTART;TZID=America/Denver:20250910T160000 DTEND;TZID=America/Denver:20250910T170000 DTSTAMP:20260922T150858Z SUMMARY:Virtual Cells in the era of AI DESCRIPTION:Speaker: Berton Earnshaw\, University of Utah and Recursion\n\nCreating virtual cells has long been a goal of the computational research community that unfortunately remains unachieved given the daunting complexity and scale of cellular biology. Nevertheless, recent advances in AI, computing power, lab automation, and high-throughput cellular profiling provide … LOCATION:ASB 210 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20250911T160000-carsten-peterson@math.utah.edu DTSTART;TZID=America/Denver:20250911T160000 DTEND;TZID=America/Denver:20250911T170000 DTSTAMP:20260922T150858Z SUMMARY:Quantum ergodicity in the Benjamini–Schramm limit in higher rank DESCRIPTION:Speaker: Carsten Peterson\, Institut de Mathématiques de Jussieu - Paris Rive Gauche\n\nOriginally, quantum ergodicity referred to the equidistribution of Laplacian eigenfunctions with large eigenvalue on manifolds with ergodic geodesic flow, such as hyperbolic surfaces. The pioneering work of Anantharaman–Le Masson '15 brought such ideas to the setting of (regular) graphs. However, … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20250925T160000-jessica-fintzen@math.utah.edu DTSTART;TZID=America/Denver:20250925T160000 DTEND;TZID=America/Denver:20250925T170000 DTSTAMP:20260922T150858Z SUMMARY:An introduction to representations of p-adic groups DESCRIPTION:Speaker: Jessica Fintzen\, University of Bonn\n\nAn explicit understanding of the (category of all smooth, complex) representations of p-adic groups provides an important tool not just within representation theory. It also has applications to number theory and other areas, and in particular enables progress on various different forms of the … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251002T160000-gilles-francfort@math.utah.edu DTSTART;TZID=America/Denver:20251002T160000 DTEND;TZID=America/Denver:20251002T170000 DTSTAMP:20260922T150858Z SUMMARY:The fraught history of brittle fracture DESCRIPTION:Speaker: Gilles Francfort\, Flatiron Institute\n\nAttempting to rationalize how and predict when rupture occurs in a solid has been a frustrating exercise since the early 19th century post-Cauchy dawn of fracture mechanics. I will attempt to briefly retrace that history with an emphasis on its equally frustrating interplay with the available … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251023T160000-nathan-kutz@math.utah.edu DTSTART;TZID=America/Denver:20251023T160000 DTEND;TZID=America/Denver:20251023T170000 DTSTAMP:20260922T150858Z SUMMARY:Shallow Recurrent Decoders for the Automated Discovery of Physical Models DESCRIPTION:Speaker: Nathan Kutz\, University of Washington\n\nA major challenge in the study of science and engineering systems is that of model discovery: turning data into dynamical models that are not just predictive, but provide insight into the nature of the underlying physics and dynamics that generated the data. We introduce a number of data-driven … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251030T160000-paul-balmer@math.utah.edu DTSTART;TZID=America/Denver:20251030T160000 DTEND;TZID=America/Denver:20251030T170000 DTSTAMP:20260922T150858Z SUMMARY:Classifying wild categories DESCRIPTION:Speaker: Paul Balmer\, University of California, Los Angeles\n\nIn many, if not most, areas of mathematics there are just too many objects of study to expect a meaningful classification up to isomorphism. Too many topological spaces, too many modules (over a fixed ring), too many representations (of a fixed group), etc, etc. We shall see how mathematicians have … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251106T160000-aaron-pollack@math.utah.edu DTSTART;TZID=America/Denver:20251106T160000 DTEND;TZID=America/Denver:20251106T170000 DTSTAMP:20260922T150858Z SUMMARY:The arithmetic of certain automorphic forms DESCRIPTION:Speaker: Aaron Pollack\, University of California, San Diego\n\nSuppose G is a non-compact semisimple Lie group, and let G (ℤ) in G be an appropriate infinite discrete subgroup. An automorphic form on G is a complex valued smooth function on G that is left invariant by G (ℤ) and satisfies some particular linear differential equation. They are key players in the … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251113T160000-kevin-miller@math.utah.edu DTSTART;TZID=America/Denver:20251113T160000 DTEND;TZID=America/Denver:20251113T170000 DTSTAMP:20260922T150858Z SUMMARY:Adaptive algorithms for data summarization DESCRIPTION:Speaker: Kevin Miller\, Brigham Young University\n\nClustering, low-rank approximation, and nonnegative matrix factorization can be phrased as data summarization problems based on selecting a small number of prototypes from a large data set. We provide a unified formulation of these problems and many others. Natural algorithms for solving these … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251120T160000-amber-smith@math.utah.edu DTSTART;TZID=America/Denver:20251120T160000 DTEND;TZID=America/Denver:20251120T170000 DTSTAMP:20260922T150858Z SUMMARY:Uncovering Infection Dynamics through Parameter Estimation and Virtual Patients DESCRIPTION:Speaker: Amber Smith\, University of Tennessee Health Science Center\n\nUnderstanding infection dynamics requires mathematical tools that can translate varying degrees of experimental and clinical data into meaningful biological insight. I will discuss approaches for estimating key parameters in within-host models of respiratory infections using simulated annealing and … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT BEGIN:VEVENT UID:20251204T160000-jing-tao@math.utah.edu DTSTART;TZID=America/Denver:20251204T160000 DTEND;TZID=America/Denver:20251204T170000 DTSTAMP:20260922T150858Z SUMMARY:From 2×2 matrices to infinite-type surfaces DESCRIPTION:Speaker: Jing Tao\, University of Oklahoma\n\nTo every topological surface one can associate a group called the mapping class group (sometimes called the modular group), consisting of homeomorphisms of the surface up to isotopy. In the case of the torus, this group is SL(2,ℤ), whose elements fall into three dynamical types detected by the … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2025-fall/ END:VEVENT END:VCALENDAR
