Matematica) Mauro Porta Seminario di geometria - Higher analytic stacks and GAGA theorems 22-Jan-2015 - 15:00 - Aula Magna (Dip. Matematica) Angelo Vistoli La figura e l’opera di Alexander Grothendieck 28-Jan-2015 - 16:00 - Sala Seminari (Dip. Matematica) Julien Korinman Decomposition of quantum representations into irreducible factors Seguono più dettagli sul seminario di domani. a presto, Bruno ------- SYMMETRIES OF HYPERBOLIC 4-MANIFOLDS Wednesday, January 14, 2015 Ora Inizio: 16:00 Ora Fine: 17:00 Aula: Sala Riunioni (Dip. Matematica) SEMINARI DI GEOMETRIA Relatore: Leone Slavich We will introduce a construction which produces a family of arithmetic, non-compact hyperbolic 4-manifolds, such that every finite group G is realized as the symmetry group of some member of this family. This allows us to obtain asymptotic bounds which relate the order of a finite group G with the minimal volume of a hyperbolic 4-manifold realizing G as its symmetry group. The construction uses very accessible techniques: basic hyperbolic geometry on one hand, and the combinatorial properties of simplicial complexes on the other.

Roberto ---------- Forwarded message ---------- Date: Thu, 11 Dec 2014 15:44:49 +0100 From: Tommaso Pacini <tommaso.pacini(a)sns.it> To: frigerio(a)dm.unipi.it, Daniele Angella <daniele.angella(a)gmail.com> Subject: Fwd: Two Topology Postdocs at Imperial ---------- Forwarded message ---------- From: Buck, Dorothy E <d.buck(a)imperial.ac.uk> Date: 2014-12-11 15:40 GMT+01:00 Subject: Two Topology Postdocs at Imperial To: "Buck, Dorothy E" <d.buck(a)imperial.ac.uk> Hello friends and colleagues, I hope this finds you all near the end of an exhilirating term and looking forward to a peaceful holiday. I am currently advertising for two 2-3year postdoctoral positions with my group at Imperial College London. This position is funded from my recent large Leverhulme grant on Knotted DNA. The start date is flexible. The postdoc will use their experience in 3-manifold topology, and be interacting with a large interdisciplinary team of biologists and topologists. (No prior biological experience necessary, although regular discussions with our collaborating experimental lab will be expected). This is a predominantly research postdoc with minimal teaching. Travel & computer funds are also included. Please advertise this to your colleagues and mailing lists, and if you know of any good candidates, please encourage them to apply, and/or email me (d.buck(a)imperial.ac.uk) with any further questions. The deadline is 22 December 2014. The jobs are advertised here: http://eims.ams.org/jobs/6658867/research-associate-in-mathematics here https://www.mathjobs.org/jobs/jobs/6803 and here: http://www.jobs.ac.uk/job/AKA639/research-associate-in-mathematics/ Thanks very much, and happy holidays!

buondì, vi segnalo il seminario di geometria di oggi. a presto, Bruno ------- Titolo: Volume simpliciale Lipschitz e principio di proporzionalità per varietà complete. Tuesday, December 9, 2014 Orario: 14:00 - 15:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Federico Franceschini (Università di Pisa) Abstract: Darò la definizione e le principali proprietà del volume simpliciale. Poi parlerò del principio di proporzionalità di Gromov per varietà riemanniane chiuse, e di una sua versione al caso di varietà complete non-positivamente curve a volume finito dato da Clara Löh e Roman Sauer. Infine, farò vedere come la loro dimostrazione può essere adattata rimuovendo le ipotesi sulla curvatura.

seminario domani + cambio giorno per l'anno prossimo
by Bruno Martelli 01 Dec '14

01 Dec '14

buondì, i seminari settimanali di geometria/topologia proseguiranno come sempre ogni martedì alle 14 fino al 16 dicembre. Riprenderemo poi *mercoledì* 14 gennaio. I seminari saranno quindi ogni *mercoledì alle 16* (almeno fino a quando non saranno definiti gli orari dei corsi del II semestre). Allego le informazioni sul seminario di domani. a presto, Bruno ---- SEMINARIO DI GEOMETRIA Tuesday, December 2, 2014 Ora Inizio: 14:00 Ora Fine: 15:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Stefan Behrens (Alfréd Rényi Institute, Budapest) Titolo: Elimination of cusps in dimension 4 and its applications Abstract: In recent years, low dimensional topologists have become interested in the study of "generic" smooth maps to surfaces. The approach is similar to Morse theory, only with two dimensional target. In this talk, I will discuss a specific problem in the 4-dimensional context which is analogous to the (uniqueness of) cancellation of critical points of Morse functions. I will also indicate applications to certain pictorial descritpions of 4-manifolds in terms of curve configurations on surfaces. This is joint work with Kenta Hayano.
