Fwd: Seminario informale di topologia mercoledì alle 11
by Bruno Martelli 15 Jun '21

Buonasera, Il seminario di domani alle 11 è confermato e c'è posto per tutti quelli che mi hanno fatto richiesta. Sarà anche trasmesso su google meet a questo indirizzo: https://meet.google.com/xsu-ubdz-grm (a meno ovviamente di inconvenienti tecnici) A domani, Bruno ---------- Forwarded message --------- From: Bruno Martelli <bruno.martelli(a)unipi.it> Date: Fri, Jun 11, 2021 at 5:02 PM Subject: [Geometria_pisa] Seminario informale di topologia mercoledì alle 11 To: Geometria <Geometria_Pisa(a)mail.dm.unipi.it> Buongiorno, Mercoledì prossimo alle 11 in Aula Magna Ludovico Battista terrà un seminario informale in cui ci spiegherà come sia possibile dimostrare la rigidità di varietà iperboliche di volume infinito in dimensione 4 a 5 abbastanza complesse. In Aula Magna ci sono massimo 25 posti e confido che siano sufficienti, chiedo però alle persone interessate di comunicarmi la loro presenza entro lunedì sera (anche perché vorrei usare l'aula lo stesso giorno anche per fare esami). Se qualcuno vuole seguire on-line basta che mi scriva (entro martedì) e ci adoperiamo con l'attrezzatura. Seguono titolo e abstract. A presto, Bruno ---- Titolo: Infinitesimal Deformations of Hyperbolic Manifolds Abstract: in the last two years, the refinement of a tool due to Jankiewicz - Norin - Wise based on Betsvina - Brady theory led to important results. This work culminated with the amazing example of Italiano - Martelli - Migliorini of a Hyperbolic 5-Manifold M which fibers over S^1. The importance of the existence of such a manifold appears to go far beyond the world of Hyperbolic Manifolds. One interesting aspect of this family of examples is that they can be manipulated combinatorially. This allows us to study the dimension of infinitesimal deformations of the hyperbolic structure of the cover M̃ associated to the map M -> S^1. The complexity of the task, though, required the exploitation of a series of methods to overcome the computational problems. In particular, we will talk about the Groupoid associated with a cube complex and how we used it to obtain the rigidity of M̃.

Seminario Karl Schwede
by Amos Turchet 07 Apr '21

07 Apr '21

Cari colleghi, vi segnalo il seguente seminario che potrebbe essere di interesse: SEMINARIO Karl Schwede (University of Utah) Titolo: Recent progress in mixed characteristic higher dimensional algebraic geometry geometry Giovedi' 8 Aprile 2021 ORE 18:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre (online) Abstract In characteristic zero birational algebraic geometry, Kawamata-Viehweg vanishing is a centrally important tool. For some applications in characteristic p > 0, one may use Frobenius and perturbations as a replacement for resolution of singularities and Kawamata-Viehweg vanishing. This talk will show how to use Bhatt's vanishing theorem for absolute integral closures mixed characteristic as a replacement for resolutions and Kawamata-Viehweg vanishing theorems in a number of applications. This is joint work with B. Bhatt, L. Ma, Z. Patakfalvi, K. Tucker, J. Waldron and J. Witaszek.
