SUMMARY:Xuesen Na
DESCRIPTION:Xuesen Na (University of Maryland) \nLimiting configuration of SU(1\,2) Higgs bundles \nAbstract: The moduli space of Higgs bundles\, or the space of solutions of Hitchin equations has been a focus of intensive studies in algebraic geometry\, symplectic geometry and topology. Recently the asymptotics near the ends of the moduli space has been investigated by studying behavior of solutions for (E\,t\Phi) as $t\to\infty$ by Mazzeo et al (2014)\, Mochizuki (2016) and Fredrickson (2018) for some cases of SL(n\,C) Higgs bundles.\nIn this talk I will present a new result of the limiting behavior of solutions SU(1\,2) Hitchin equation\, as a first step of extending the study to the G-Higgs bundle with G a real rank-one Lie group. The proof relies on construction of approximate solutions by gluing local models on disks to decoupled solutions which converge to limiting configuration after appropriate scaling. A by-product of the study is an explicit description of spectral data of generic SU(1\,2) Higgs bundle by Hecke transformations. \nZoom details: \nhttps://uni-frankfurt.zoom.us/j/94748325596?pwd=NnM1VklLc1c2YXdHclMva2wwTzcrQT09\n\n\nMeeting-ID: 947 4832 5596\nPasscode: 176149\n\n  \n

SUMMARY:Fabio Bernasconi
DESCRIPTION:GAUS-Seminar talk by Fabio Bernasconi (University of Utah) \nLog liftability for del Pezzo surfaces and applications to singularities in positive characteristic \nAbstract: In a recent work with Arvidsson and Lacini\, we proved a liftability result to characteristic zero for singular del Pezzo surfaces over perfect fields of characteristic $p>5$. I will explain exactly what notion of liftability we use for singular surfaces (and pairs)\, and I will sketch some parts of the proof.\nFrom this\, I will explain the importance of this result for positive characteristic birational geometry: we prove a Kawamata-Viehweg vanishing theorem for such surfaces that I successively used\, in a work with Kollár\, to deduce properties of singularities of klt threefolds and new liftability results for threefolds Mori fibre spaces in positive characteristic. \nZoom details: \nhttps://uni-frankfurt.zoom.us/j/95464396687?pwd=eno5NGpQdHBmVFlaT1pBU0xlcG15Zz09 \nMeeting ID: 954 6439 6687\nPasscode: 813167

SUMMARY:Pre-Seminar for the Ruth Moufang Lectures
DESCRIPTION:In the very first instalment of the Ruth Moufang Lectures\, Jennifer Balakrishnan will talk about rational points on curves. In the tradition of the “Gingko-Seminar”\, we offer a “pre-seminar” as preparation consisting of  two 45 minute talks. The pre-seminar is aimed at PhD students and PostDocs\, as well as interested Bachelor and Master students.\n \n1. What is… a p-adic number? (Theresa Kumpitsch) \nThe p-adic numbers were invented (or discovered depending on your philosophy) at the beginning of the twentieth century by Kurt Hensel following the observation that that numbers behave similar to functions in many ways. In this short introduction to p-adic numbers we want to explore this analogy\, learn about different ways of expressing p-adic numbers\, look at lots of examples and get a sense of why they play a role in the theory of Diophantine equations. \n2. What is… an algebraic curve? (Martin Lüdtke) \nRoughly\, an algebraic curve is a 1-dimensional shape defined by polynomial equations. Examples are parabolas\, hyperbolas\, elliptic curves\, or the Fermat curves defined by x^n + y^n = z^n. We want to explore first the geometry of curves and discover the genus as a discrete invariant. We then turn to the problem of finding rational solutions to equations in two variables. We discuss several examples and see how the set of rational solutions is governed by the geometry of the associated algebraic curve. \nZoom coordinates: \nhttps://uni-frankfurt.zoom.us/j/92910007294?pwd=MTFwU2VKR3MvU1JWanZIUDlmYms4UT09  Meeting ID: 929 1000 7294Passcode: 931095

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Lennart Gehrmann (University of Duisburg-Essen) \nRigid meromorphic cocycles for orthogonal groups \nAbstract: I will talk about a generalization of Darmon and Vonk’s notion of rigid meromorphic cocycles to the setting of orthogonal groups. After giving an overview over the general setting I will discuss the case of orthogonal groups attached to quadratic spaces of signature (3\,1) in more detail. This is joint work with Henri Darmon and Mike Lipnowski.
