Seminario oggi
by Bruno Martelli 12 Oct '17

12 Oct '17

Cari, Vi ricordo il seminario di oggi pomeriggio. A presto, Bruno ---- 12-Oct-2017 - 16:00 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> On corks with low shadow-complexity <http://www.dm.unipi.it/webnew/it/seminari/corks-low-shadow-complexity> Hironobu Naoe (Tohoku University, Japan) A cork is a contractible Stein domain that gives arise to exotic pairs of 4-manifolds. The first example was found by Akbulut. It is known that any two exotic, simply-connected, closed 4-manifolds are related by a cork twist. We show that there are no corks having shadow-complexity zero. We also show that there are infinitely many corks having shadow-conplexity 1 and 2.

tablet del gruppo
by Carlo Petronio 09 Oct '17

09 Oct '17

Cari geometri, piccolo update sui tablet del gruppo: - quello che ha Camtasia installato (il software di registrazione) ora ce l'ha Rita, e lo lascia quando non lo usa in un posto in studio che dirà lei a chi di voi magari ne avesse bisogno; - quello che non ha Camtasia adesso è nel mio studio, nella borsa color vinaccia nell'armadio, ma io non lo uso, quindi chi vuole può venire a prenderlo; suggerirei però se possibile di mettere Camtasia anche su questo. Filippo ha ritrovato la licenza, che allego. Bisognerebbe provare a vedere se con la stessa licenza si può installare di nuovo. Se ne può occupare qualcuno? Si può anche chiedere aiuto ad Andrea Batistini (passando per help - SID - Polo2 <help.polo2(a)ticket.unipi.it>): è quello più esperto di Windows, ed è molto gentile e competente. Sarebbe meglio farlo subito per non doverlo fare in extremis quando ce n'è bisogno.

Era un'unica licenza. Non mi ricordo se occorra fare delle operazioni online per registrare la licenza su una macchina (perdendo quindi la possibilità di usare la licenza una seconda volta). Però forse la licenza da diritto ad utilizzare/installare il programma su più macchine?

Seminari oggi e giovedì prossimo
by Bruno Martelli 05 Oct '17

05 Oct '17

Buondì, Vi annuncio che oggi (alle 16) e giovedì prossimo (sempre alle 16) ci saranno due seminari sulle 4-varietà. Seguono più informazioni. A presto, Bruno ---- 05-Oct-2017 - 16:00 Sala Seminari (Dip. Matematica) Rohlin’s theorem and non-simply connected 4-manifolds Danny Ruberman (Brandeis University) Most applications of gauge theory in 4-dimensional topology are concerned with simply-connected manifolds with non-trivial second homology. I will discuss the opposite situation, first describing the classical Rohlin invariant for manifolds with first homology = Z and vanishing second homology. I will give an interpretation in terms of a Seiberg-Witten theory, with an unusual index-theoretic correction term. I will discuss recent work with Jianfeng Lin and Nikolai Saveliev giving a new formula for this invariant in terms of monopole homology. ---- 12-Oct-2017 - 16:00 Sala Seminari (Dip. Matematica) On corks with low shadow-complexity Hironobu Naoe (Tohoku University, Japan) A cork is a contractible Stein domain that gives arise to exotic pairs of 4-manifolds. The first example was found by Akbulut. It is known that any two exotic, simply-connected, closed 4-manifolds are related by a cork twist.

Fwd: Postdoctoral felloships in Madrid
by Bruno Martelli 20 Jul '17

20 Jul '17

Buondì, Vi giro una mail su delle borse post-doc interessanti a Madrid. Si tratta di "Teoria dei Gruppi" ma visti i nomi è da intendersi in senso molto geometrico/topologico, quindi molti geometri potrebbero partecipare. Bruno ---------- Forwarded message ---------- From: Javier Aramayona <javier.aramayona(a)uam.es> Date: Thu, Jul 20, 2017 at 5:18 AM Subject: Postdoctoral felloships in Madrid To: javier.aramayona(a)uam.es Dear all, The "la Caixa" Foundation has recently advertised a call for 20 postdoctoral fellowships in various areas, including mathematics. The details of the call (in English) can be found at: https://obrasociallacaixa.org/en/educacion-becas/becas/becas -de-posgrado/becas-postdoctorales-junior-leader/descripcion-del-programa The relevant scheme (Incoming Programme) is open to researchers who obtained their Ph.D. at some point between 2 October 2011 and 2 October 2014. The fellowships are of 3 years duration, with a competitive salary, and a generous travel grant. The selection process will be carried out by an external panel of experts, and we expect it will be extremely competitve. We encourage young researchers with interests in the general area of group theory to submit an application. If selected, the applicant would join the Group Theory group at UAM-ICMAT, consisting of: Andrei Jaikin (andrei.jaikin(a)uam.es) : asymptotic group theory, profinite groups, L2 invariants. Javier Aramayona (javier.aramayona(a)uam.es) : mapping class groups, curves on surfaces, Teichmüller spaces. Yago Antolín (yago.antolin(a)uam.es) : geometric and combinatorial group theory, formal languages in finitely-generated groups. We would be grateful if you could forward this information to any interested candidates. Candidates should apply using the online application system that can be found from the link above, indicating that they would like to work within the Group Theory group at ICMAT. Please note that the deadline is 2nd October 2017. Thanks in advance, and best regards, Andrei Jaikin, Javier Aramayona, Yago Antolín

Seminari dei Baby-Geometri (ultimo doppio appuntamento)
by Marco Moraschini 13 Jun '17

13 Jun '17

Cari tutti, vi segnaliamo un doppio appuntamento dei seminari dei Baby Geometri per Giovedì 15 Giugno che concluderà la sessione di incontri per quest'anno accademico. Di seguito trovate gli speakers e i titoli dei seminari con rispettivi abstract. **Giovedì 15 Giugno ore 15:00 in Aula Riunioni (Dipartimento di Matematica) Sabine Braun (KIT) - L^2-Betti Numbers and Riemannian Volume Abstract: Gromov raised the question whether there is a universal bound for the L^2-Betti numbers of an aspherical manifold by its simplicial volume. A positive answer would yield, in combination with Gromov's main inequality, an upper bound of L^2-Betti numbers of an aspherical manifold by its Riemannian volume provided a lower Ricci curvature bound. While the above conjecture remains open, the implication was shown by Sauer using so-called randomization techniques. After a short introduction to L^2-Betti numbers, I will address the randomization techniques and new developments around curvature-free versions of the main inequality for L^2-Betti numbers. **Giovedì 15 Giugno 16:30 in Aula Riunioni Mirko Mauri (Imperial College London) - Gruppo fondamentale del link di singolarità Abstract: Ogni singolarità (isolata) è omeomorfa al cono sopra il bordo di un suo intorno locale detto link. Una serie di evidenze mostra l’esistenza di una forte connessione tra la topologia del link e la natura algebrica della singolarità. In particolare, una congettura ancora aperta di Kollár afferma che il gruppo fondamentale del link è finito se la singolarità è di tipo klt. Tali singolarità sono di grande rilevanza per il programma dei modelli minimali (MMP). In questa esposizione calcoleremo esplicitamente alcuni esempi e presenterò la strategia induttiva proposta da Zhiyu Tian e Chenyang Xu. Tutti gli interessati sono invitati a partecipare. Per saperne di più sui prossimi seminari scrivete ad uno degli organizzatori o consultate le pagine: http://blog.phc.unipi.it/babygeometri/ http://gecogedi.dimai.unifi.it/seminars/ Mailing-list: babygeom(a)poisson.phc.unipi.it Saluti, Carlo Collari, Marco Moraschini e Nicoletta Tardini
