These dynamics are quantum mechanical and present many surprising phenomena without classical analogues. I will present analytical and numerical work clarifying these dynamics in three novel materials … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230124T160000-federico-ardila@math.utah.edu DTSTART;TZID=America/Denver:20230124T160000 DTEND;TZID=America/Denver:20230124T170000 DTSTAMP:20260922T150858Z SUMMARY:The geometry of geometries: matroid theory, old and new DESCRIPTION:Speaker: Federico Ardila\, San Francisco State University\n\nThe theory of matroids or combinatorial geometries originated in linear algebra and graph theory, and has deep connections with many other areas, including field theory, matching theory, submodular optimization, Lie combinatorics, and total positivity. Matroids capture the combinatorial essence that … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230125T160000-raghav-venkatraman@math.utah.edu DTSTART;TZID=America/Denver:20230125T160000 DTEND;TZID=America/Denver:20230125T170000 DTSTAMP:20260922T150858Z SUMMARY:Variational principles in materials science with small parameters: a case study of liquid crystals DESCRIPTION:Speaker: Raghav Venkatraman\, New York University\n\nVariational principles are ubiquitous and are at the heart of a broad range of applications. Common challenges in the analysis of such principles is the interplay between the effects of nonconvexity, nonlocality, spatial heterogeneity, and even randomness. What results is a diverse array of … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230216T160000-samuel-grushevsky@math.utah.edu DTSTART;TZID=America/Denver:20230216T160000 DTEND;TZID=America/Denver:20230216T170000 DTSTAMP:20260922T150858Z SUMMARY:Moduli of Riemann surfaces with a differential DESCRIPTION:Speaker: Samuel Grushevsky\, Stony Brook University\n\nThe moduli space of complex curves together with a differential naturally appears as an object of study in algebraic and symplectic geometry, and is the phase space of Teichmuller dynamics. We will discuss degenerations of differentials, as Riemann surfaces degenerate to nodal ones, and resulting … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230221T160000-blerta-shtylla@math.utah.edu DTSTART;TZID=America/Denver:20230221T160000 DTEND;TZID=America/Denver:20230221T170000 DTSTAMP:20260922T150858Z SUMMARY:An introduction and invitation to Quantitative Systems Pharmacology DESCRIPTION:Speaker: Blerta Shtylla\, Pfizer\n\nQuantitative systems pharmacology (QSP) encompasses multiscale mechanism-based modeling that couples pharmacology with mathematical modeling of biological processes implicated in diseases. QSP models seek to address a diverse set of problems in the discovery and development of therapies and are … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230223T160000-s%C3%A1ndor-kov%C3%A1cs@math.utah.edu DTSTART;TZID=America/Denver:20230223T160000 DTEND;TZID=America/Denver:20230223T170000 DTSTAMP:20260922T150858Z SUMMARY:A journey to the Devil's Domain DESCRIPTION:Speaker: Sándor Kovács\, University of Washington\n\nMax Noether said that algebraic curves were created by God and algebraic surfaces by the Devil. In this talk I will show some modern evidence supporting this statement. A moduli space is a parameter space for isomorphism classes of certain types of objects. Moduli spaces of curves have received a … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230302T160000-autumn-kent@math.utah.edu DTSTART;TZID=America/Denver:20230302T160000 DTEND;TZID=America/Denver:20230302T170000 DTSTAMP:20260922T150858Z SUMMARY:The 0π-theorem DESCRIPTION:Speaker: Autumn Kent\, University of Wisconsin - Madison\n\nA celebrated theorem of Thurston tells us that among the many ways of filling in cusps of hyperbolic 3--manifolds, all but finitely many of them produce hyperbolic manifolds once again. This finiteness may be refined in a number of ways depending on the "shape" of the cusp, and I'll give a light and … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230323T160000-richard-tsai@math.utah.edu DTSTART;TZID=America/Denver:20230323T160000 DTEND;TZID=America/Denver:20230323T170000 DTSTAMP:20260922T150858Z SUMMARY:Implicit boundary integral methods and applications DESCRIPTION:Speaker: Richard Tsai\, University of Texas at Austin\n\nI will review a general framework that can be used to develop numerical methods for various problems involving non-parametrically defined surfaces. The main idea is to formulate appropriate extensions of a given problem defined on a surface to ones in the narrow band of the surface in the embedding … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230330T160000-manish-patnaik@math.utah.edu DTSTART;TZID=America/Denver:20230330T160000 DTEND;TZID=America/Denver:20230330T170000 DTSTAMP:20260922T150858Z SUMMARY:Automorphic Forms on Loop Groups DESCRIPTION:Speaker: Manish Patnaik\, University of Alberta\n\nThe loop group, or the space of maps from the circle into a Lie group G, is one of the most tractable examples of an infinite-dimensional group of continuous symmetries. After reviewing some basic facts about such loop groups (and their central extensions), we shall focus on their arithmetic theory … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230406T160000-soumik-pal@math.utah.edu DTSTART;TZID=America/Denver:20230406T160000 DTEND;TZID=America/Denver:20230406T170000 DTSTAMP:20260922T150858Z SUMMARY:An invitation to entropy-regularized optimal transport DESCRIPTION:Speaker: Soumik Pal\, University of Washington\n\nThe theory of Monge-Kantorovich optimal transport has become widely popular in various applications in statistics and data science. Part of this popularity is due to the computational efficiency of a regularized version of the problem with the entropy serving as a penalty function. It turns out that … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230414T120000-wei-kuo-chen@math.utah.edu DTSTART;TZID=America/Denver:20230414T120000 DTEND;TZID=America/Denver:20230414T130000 DTSTAMP:20260922T150858Z SUMMARY:Computational perspective of the local magnetization in the Sherrington-Kirkpatrick model DESCRIPTION:Speaker: Wei-Kuo Chen\, University of Minnesota\n\nSpin glasses are disordered spin systems originally introduced by theoretical physicists with the aim to explain some unusual magnetic behavior of certain alloys, such as CuMn and AuFe.

Just as Brownian motion is a special kind of random path, there is a similarly special … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT BEGIN:VEVENT UID:20230425T160000-ellen-eischen@math.utah.edu DTSTART;TZID=America/Denver:20230425T160000 DTEND;TZID=America/Denver:20230425T170000 DTSTAMP:20260922T150858Z SUMMARY:Some congruences and consequences in number theory and beyond DESCRIPTION:Speaker: Ellen Eischen\, University of Oregon\n\nIn the middle of the nineteenth century, Kummer observed striking congruences between certain values of the Riemann zeta function, which have important consequences in number theory. Recent advances in arithmetic geometry and number theory have revealed similarly consequential congruences in the … LOCATION:JWB 335 URL:https://www.math.utah.edu/research/colloquia/2023-spring/ END:VEVENT END:VCALENDAR
