[Indico] Luca Schaffler, Boundary divisors in the stable pair compactification of the moduli space of Horikawa surfaces, 04/05/2022, 14:30 Europe/Rome

Title: Boundary divisors in the stable pair compactification of the moduli space of Horikawa surfaces, Speaker(s): Luca Schaffler, Roma 3, Date and time: 4 May 2022, 14:30 (Europe/Rome), Lecture series: Algebraic and Arithmetic Geometry Seminar, Venue: Dipartimento di Matematica (Aula Magna). You can access the full event here: https://events.dm.unipi.it/e/71 Abstract -------- Smooth minimal surfaces of general type with $K^2=1$, $p_g=2$, and $q=0$ constitute a fundamental example in the geography of algebraic surfaces, and the 28-dimensional moduli space $M$ of their canonical models admits a geometric and modular compactification $\overline{M}$ by stable surfaces. Franciosi-Pardini-Rollenske classified the Gorenstein stable degenerations parametrized by it, and jointly with Rana they determined boundary divisors parametrizing irreducible stable surfaces with a unique T-singularity. In this talk, we continue with the investigation of the boundary of $\overline{M}$ constructing eight new irreducible boundary divisors parametrizing reducible surfaces. Additionally, we study the relation with the GIT compactification of $M$ and the Hodge theory of the degenerate surfaces that the eight divisors parametrize. This is joint work in progress with Patricio Gallardo, Gregory Pearlstein, and Zheng Zhang. -- Indico :: Email Notifier https://events.dm.unipi.it/e/71

Seminario mercoledì prossimo
by Bruno Martelli 29 Apr '22

29 Apr '22

Buondì, Segnalo un seminario di geometria per mercoledì prossimo. A presto, Bruno 04-May-2022 - 16:00 Sala Seminari (Dip. Matematica) Simplicial volume and aspherical manifolds Marco Moraschini Simplicial volume is a homotopy invariant for compact manifolds introduced by Gromov in the early 80s. It measures the complexity of a manifold in terms of singular simplices. Since simplicial volume behaves similarly to the Euler characteristic, a natural problem is to understand the relation between these two invariants. More precisely, a celebrated question by Gromov (~’90) asks whether all oriented closed connected aspherical manifolds with zero simplicial volume also have vanishing Euler characteristic. In this talk, we will describe the problem and we will show counterexamples to some variations of the previous question. Moreover, we will describe some new strategies to approach the problem as well as the relation between Gromov’s question and other classical problems in topology. This is part of a joint work with Clara Löh and George Raptis.

[Indico] Marco D'Addezio, Parabolicity conjecture of F-isocrystals, 27/04/2022, 14:30 Europe/Rome
by francesco.sala＠unipi.it 26 Apr '22

Title: Parabolicity conjecture of F-isocrystals, Speaker(s): Marco D'Addezio, Université de Paris, Date and time: 27 Apr 2022, 14:30 (Europe/Rome), Lecture series: Algebraic and Arithmetic Geometry Seminar, Venue: Dipartimento di Matematica (Aula Magna). You can access the full event here: https://events.dm.unipi.it/e/70 Abstract -------- In the last years the theory of crystalline cohomology and F-isocrystals had a great development. I will present a new result concerning the algebraic monodromy groups of F-isocrystals. I will start with a quick introduction on crystalline cohomology, F-isocrystals, and overconvergent F-isocrystals. Subsequently, I will recall the definition of monodromy groups of F-isocrystals (which uses the theory of Tannakian categories) and in the end I will explain the main theorem, the applications, and some ideas of the proof. -- Indico :: Email Notifier https://events.dm.unipi.it/e/70

Annuncio Seminario Caputi
by Carlo Collari 12 Apr '22

12 Apr '22

Buongiorno a tutti, inoltro l'annuncio del seminario di Luigi Caputi che si terrà domani (13 Aprile 2022) alle 16:00 nell'Aula Magna del Dipartimento. In allegato titolo e abstract Saluti, Carlo Collari Titolo: Coarse Homology Theories Relatore: Luigi Caputi (University of Aberdeen) Abstract: Coarse spaces, first introduced by J. Roe for studying index-type theorems, have recently found applications also in K-theory and assembly map conjectures. The main tool in such applications is given by coarse homology theories, homological invariants of coarse spaces. Goal of the talk is to define coarse homology theories using the homotopical approach developed by U. Bunke and A. Engel. The main example will be coarse algebraic K-theory.
