Geometria

 We will describe the geometry of so-called formal-analytic arithmetic surfaces, which are an arithmetic analogue of neighborhoods of curves embedded in complex surfaces. We will study those under some positivity assumptions, proving a simple inequality that will allow us to prove an algebraization theorem that generalizes a result of Calegari-Dimitrov-Tang, as well, as bounds on fundamental groups. This is joint work with Jean-Benoît Bost. 


Il seminario sarà presentato in presenza nell'aula M3. Tutti gli afferenti all'università Roma Tre potranno accedere previa esibizione del greenpass. Gli esterni che fossero interessati a partecipare possono contattare gli organizzatori all'email amos.turchet@uniroma3.it.
