Thanks in advance and best wishes, Jean-Marc ------------------------------------- We currently have an opening for 3 postdoctoral positions in Geometry at the University of Luxembourg (group of Jean-Marc Schlenker). All positions are for 2 years, with a possible extension to a third year for two positions, and possible extension to a maximum of 5 years (in total) for the third position. Starting date is Sept 1, 2021 or later. Two positions are funded by a project on convex domains and convex surfaces in hyperbolic geometry. Preference will be given to candidates showing strong promises with a track record in the areas of geometric structures on low-dimensional manifolds, geometric analysis, Teichm\"uller theory, or related fields. The postdocs recruited will be expected to participate in the scientific activities of the mathematics department, as well as have a limited contribution to its teaching missions (max 70h/year). They will benefit from an excellent atmosphere in a dynamic department, funding for travel, invitations or scientific activities, as well as a very competitive salary. Applications received by February 15, 2021 will be given preference.

Seminario di geometria algebrica e aritmetica, 11 novembre
by Tamas Szamuely 04 Nov '20

04 Nov '20

Cari tutti, Il prossimo seminario di geometria algebrica e aritmetica di Pisa si terrà (purtroppo di nuovo) ONLINE il mercoledì 11 NOVEMBRE 2020 alle 18:00 Programma: Giulia Sacca’ (New York): Birational Geometry of the Intermediate Jacobian fibration Link al seminario: https://meet.google.com/mgr-ybkg-brj Abstract: I will start by presenting some applications of the minimal model program to the construction of symplectic compactifications of certain Lagrangian fibrations (integrable systems) of geometric origin. One such case is that of the intermediate Jacobian fibration associated to a cubic fourfold (Donagi-Markman integrable system). In the second part of the talk, I will discuss aspects of the birational geometry of this fibration (e.g. the Mordell-Weil group). Migliori saluti, Tamás Szamuely

Seminario in presenza di geometria, mercoledì prossimo alle 11
by Bruno Martelli 11 Oct '20

11 Oct '20

Buondì, Mercoledì prossimo alle 11 si terrà un altro seminario di geometria in Aula Magna. Come sempre, chi vuole partecipare dovrà mandarmi la propria adesione entro le 17 del giorno precedente (se potete, meglio prima possibile). Il seminario verrà trasmesso in diretta e registrato in questo canale Teams: https://teams.microsoft.com/l/channel/19%3a540f44c5cea54ac09f8bb6d267f8cdaf… Nello stesso canale c'è la registrazione del seminario precedente, che rimarrà nella cartella File. Purtroppo per colpa mia nella registrazione manca il pezzo introduttivo iniziale, ma miracolosamente si riesce a seguire lo stesso. Seguono i dati del prossimo seminario. A presto, Bruno 14-Oct-2020 - 11:00 Cusps of Hyperbolic 4-Manifolds and Rational Homology Spheres <http://www.dm.unipi.it/webnew/it/seminari/cusps-hyperbolic-4-manifolds-and-…> Leonardo Ferrari By Margulis’ Lemma, a finite-volume complete hyperbolic n-manifold has a finite number of ends called cusps, each of which is diffeomorphic to the product of a flat (n-1)-manifold with the half-line. These flat manifolds are called cusp sections, and their possible configurations on hyperbolic manifolds is still very little understood. For instance, it was still not known if a hyperbolic manifold could have only rational homology spheres as cusp sections. In the 4-dimensional case, of the 10 flat 3-manifold diffeomorphism types, only the Hansche-Wendt manifold is a rational homology sphere, and it was conjectured if there existed an orientable hyperbolic 4-manifold such that all the cusps sections were such a manifold. We will introduce combinatorial tools to build manifolds by gluing copies of polytopes - a technique called colouring - and computational tools to tree-search for manifolds, thus providing an example that answers affirmatively this conjecture. Joint work with Leone Slavich and Sasha Kolpakov.

Re: [Geometria_pisa] Seminario mercoledì prossimo/registrazione
by Bruno Martelli 29 Sep '20

Caro Riccardo, Ci proviamo. Essendo un seminario informale secondo me è meglio usare la lavagna e Emanuele Paolini mi ha detto che esistono dei modi di riprendere le varie lavagne (e ci sono le istruzioni per farlo). Forse eviterei di registrare e di mettere su un canale pubblico aperto a chiunque, sempre per il carattere informale della cosa. Se ci riuscisse, si potrebbe mettere su Microsoft Stream riservato a unipi. Mercoledì mattina vado prima a vedere cosa riesco a fare, chiunque abbia dimestichezza e vuole dare una mano mi faccia sapere. E' comunque uno sforzo utile anche per i seminari successivi.
