Seminario di Geometria 30/11
by Filippo Bianchi 28 Nov '23

28 Nov '23

Carə tuttə, Giovedì 30 Novembre alle 14.30 in Aula Seminari si terrà il seminario di James Farre (Universität Heidelberg) dal titolo "Horospheres, Lipschitz maps, and laminations". Di seguito l'abstract. Every horocycle in a closed hyperbolic surface is dense, which was proved by Hedlund in the 1940's. We study the behavior of horocycle orbit closures in Z-covers of closed surfaces, and obtain a fairly complete classification of their topology and geometry. The main tool is a solution of a surprisingly delicate geometric optimization problem: finding an optimal Lipschitz map to the circle in a given homotopy class and the associated lamination of maximal stretch. I will explain the relationship between these two problems, and if time permits, I will give a novel construction of optimal circle valued Lipschitz maps using the orthogeodesic foliation construction. This is joint work with Yair Minsky and Or Landesberg featuring joint work with Aaron Calderon. Ci troveremo alle 13 in atrio per andare a pranzo con James. Le informazioni sui prossimi seminari si trovano sul sito<https://www.dm.unipi.it/categoria-evento/geometry-seminar/>. Vi aspettiamo! Buona giornata, Filippo, Giovanni e Giuseppe

---------- Forwarded message --------- From: Barbara Nelli <barbara.nelli(a)univaq.it> Date: Sun, Nov 12, 2023 at 11:18 AM Subject: European School of Differential Geometry: Granada June 24th to Jully 5th , 2024. To: Barbara Nelli <barbara.nelli(a)univaq.it> Dear Colleague, as a board member, I am pleased to inform you about the European School of Differential Geometry http://imag.ugr.es/esdg/ that will be held in Granada (Spain) from June 24th to Jully 5th , 2024. The ESDG has been approved as a Satellite Event of the ECM2024-Sevilla. The realization of this type of event is essential to maintain the vitality of Differential Geometry in Europe. The ESDG target audience is focused on young researchers, as well as Master and Doctoral students involved in the area of Differential Geometry. The ESDG will encourage the cohesion of the different research groups in Europe, having significant effects on the development of Mathematics on the continent. The idea is to create a solid and resilient event, with a clear projection in the future. The ESDG will take place every two years, each occasion in a European country. Students attending the school will have the opportunity to apply for scholarships. All the information will be available in the school webpage. Please do not hesitate to ask for additional information. I would be grateful if you could actively promote the school to attract as many participants as possible. Sincerely, Barbara Nelli

Carə tuttə, Giovedì 9 Novembre alle 14.30 in Aula Seminari si terrà il seminario di Hironobu Naoe (Chuo University) dal titolo "Shadow-complexity and trisection genus". Di seguito l'abstract. A shadow of a closed 4-manifold is a 2-complex suitably embedded in the 4-manifold, which can be treated as a combinatorial description of 4-manifolds. An invariant, called the shadow-complexity, of 4-manifolds is defined by counting certain vertices in shadows. On the other hand, a trisection is a decomposition of a 4-manifold into three handlebodies, and the intersection of the three handlebodies forms an orientable surface called the trisection surface. The trisection genus of a 4-manifold is defined as the minimum genus of all trisection surfaces. In this talk, we introduce a refined version of the shadow-complexity and give an inequality between the complexity and the trisection genus. Furthermore, we determine the complexity we introduced for some 4-manifolds. This is joint work with Masaki Ogawa. Ci troveremo alle 13 in atrio per andare a pranzo con Hironobu. Le informazioni sui prossimi seminari si trovano sul sito<https://www.dm.unipi.it/categoria-evento/geometry-seminar/>. Vi aspettiamo! Buona giornata, Filippo, Giovanni e Giuseppe

Carə tuttə, Giovedì 2 Novembre alle 14.30 in Aula Seminari si terrà il seminario di Francesco Costantino (Université Toulouse III) dal titolo "Costruzione di TQFT di dimensione 3 e 4". Di seguito l'abstract. Comincerò questo seminario ricordando la definizione delle TQFT in dimensione n e alcuni fatti generali (e.g. la definizione degli invarianti « quantistici » associati). Utilizzando poi una presentazione di Juhasz della categoria dei cobordismi darò un’idea della costruzione recente di nuove famiglie di TQFT in dimensione 2+1 e 3+1, basata su categorie di un tipo molto generale e che in dimensione 3 include per esempio le costruzioni di Turaev-Viro o più in generale di Barrett e Westbury, ma nel caso di categorie non semi-semplici. Terminerò parlando della costruzione in dimensione 4 e degli invarianti associati indicando alcune delle ostruzioni attualmente note per ottenere invarianti che siano capaci di distinguere varietà omeomorfe ma non diffeomorfe. (In collaborazione con : N. Geer, B. Patureau, B. Haioun e A. Virelizier) Ci troveremo alle 13 in atrio per andare a pranzo con Francesco. Le informazioni sui prossimi seminari si trovano sul sito<https://www.dm.unipi.it/categoria-evento/geometry-seminar/>. Vi aspettiamo! Buona giornata, Filippo, Giovanni e Giuseppe
