Seminario giovedì
by Bruno Martelli 30 Oct '17

30 Oct '17

Buondì, Vi annuncio un seminario giovedì prossimo. a presto, Bruno ---- 02-Nov-2017 - 16:00 Sala Seminari (Dip. Matematica) Minimal volume hyperbolic 4-manifolds Leone Slavich Since the volume of a hyperbolic manifold is often regarded as a measure of its complexity, it is interesting to study the examples of minimal volume. The 2 and 3-dimensional cases are well understood. In dimension four there is an abundance of examples, but we are far from classifying them. In this talk, we will survey all known examples of minimal volume hyperbolic 4-manifolds and prove that these fall into three commensurability classes. This is joint work with Stefano Riolo.

Seminario oggi

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. Ciao, Carlo -------- Messaggio Inoltrato -------- Oggetto: licenza camtasia Data: Wed, 4 Oct 2017 13:15:48 +0200 Mittente: Filippo Callegaro <callegaro(a)dm.unipi.it> A: Carlo Petronio <carlo.petronio(a)unipi.it> Ciao Carlo, questa era la licenza acquistata da Sandra due anni fa per Camtasia. 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. 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.
