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

Dear Colleagues,
The University of Virginia is advertising two positions:
==================
The geometry and topology group at the University of Virginia is hiring *two
NSF RTG research associates*. The appointments are one year long, renewable
for a total of three years. The application deadline is November 15, 2020.
Preference will be given to candidates within three years of completing
their PhD. The search targets fields which complement the research
interests of the *geometry and topology group* at UVa, which includes
*geometric
topology, algebraic topology, and geometric group theory.* Applicants must
be US citizens, nationals, or permanent residents (per NSF rules). Research
associates are expected to teach during the academic year, and to assist in
the topology Research Experience for Undergraduates during at least one
summer of their employment.
For further specifics, including instructions for applying, please visit

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

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.

Please forward to anyone who might be interested.
Best regards,

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.
Ciao,
Bruno

Buondì,
Sto organizzando alcuni seminari di geometria (soprattutto geometria
iperbolica), in presenza (!), tenuti da nostri dottorandi e studenti.
Saranno il mercoledì mattina alle 11, in Aula Magna (non tutti i
mercoledì). L'aula contiene circa 25 posti (non ricordo il numero esatto).
Lo scopo principale è permettere ai dottorandi di discutere della loro
ricerca e di progetti futuri: sarà quindi qualcosa di più informale del
solito (spero) e forse anche più specialistico - qualcosa di rilassato a
metà tra i seminari usuali e un gruppo di lavoro.
I seminari sono ovviamente aperti a chiunque, purché si seguano tutte le
solite regole ben note (mascherina, distanziamento sociale, iscrizione
all'ingresso del dipartimento, non usare mai il termine "piuttosto che" in
forma disgiuntiva).
Questo il primo seminario:
30-Sep-2020 - 11:00
A Hyperbolic 4-manifold with a perfect circle-valued Morse function
<http://www.dm.unipi.it/webnew/it/seminari/hyperbolic-4-manifold-perfect-cir…>
Ludovico Battista
Aula Magna
In dimension 3, combining the study of the geometry and the topology of
manifolds led to interesting and surprising results. The generalization of
such a link in dimension 4 seems to be a promising approach to better
understand this complicated world.
An intriguing 3-dimensional phenomenon is the existence of hyperbolic
manifolds which fiber over the circle. Such manifolds cannot exist in
dimension four, due to a constraint given by Euler Characteristic and the
Gauss - Bonnet formula. We will introduce the notion of "perfect
circle-valued Morse function", which appears to be the natural
generalization of "fibration over S^1", and we will show the existence of a
finite-volume cusped hyperbolic 4-manifold which admits such a function. To
do this we will elaborate on a recent paper of Jankiewicz - Norin - Wise
that makes use of Bestvina - Brady theory.
Joint work with Bruno Martelli.
