Seminario di geometria 28/09 e pretalk 27/09
by Filippo Bianchi 28 Sep '23

28 Sep '23

Carə tuttə, Giovedì 28 Settembre alle 14.30 in Aula Seminari si terrà il seminario di Ken Baker (University of Miami) dal titolo "Handle numbers of knots and sutured manifolds". Di seguito l'abstract. The handle number, or Morse-Novikov number, of a knot counts the minimum number of handles needed for a circular Heegaard splitting of its exterior. It may be viewed as a measure of distance from fiberedness. The rank of the top groups of the instanton and Heegaard knot Floer homologies also provide another measure. Here we show that the nearly fibered knots of the Floer sense due to Li-Ye and Baldwin-Sivek are not always nearly fibered in the handle number sense. In the process we also provide conditions for knots to have unique incompressible Seifert surfaces and show that some Floer nearly-fibered knots have incompressible Seifert surfaces of non-minimal genus. Mercoledì 27 Settembre alle 14.30 in Aula Riunioni, Ken terrà un pretalk sugli argomenti del seminario. 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

Workshop "Combinatorial algebraic topology and applications" announcement
by Carlo Collari 21 Sep '23

21 Sep '23

Dear all, We are happy to announce the workshop CATA: *Combinatorial algebraic topology and applications. *CATA is a two-days event that will be held at Centro De Giorgi in Pisa the 27th and 28th, November 2023. The workshop concerns various topics in combinatorics and algebraic topology, as well as their applications to different fields, e.g. data analysis, neural sciences and economics. The aim of the workshop is to gather researchers with common interest in the above topics, and to create an atmosphere of discussion, where to share ideas. Leó Benard (Université de Aix-Marseille) Celeste Damiani (Istituto Italiano di Tecnologia) Irakli Patchkoria (University of Aberdeen) Simona Settepanella (Università di Torino) Jason P. Smith (Nottingham Trent University) Paolo Salvatore (Università di Roma Tor Vergata) Viola Siconolfi (Politecnico di Bari) Jonathan Spreer (University of Sydney/TU Berlin) Limited funding might be available to early registered participants. If needed, please contact Luigi Caputi (luigi.caputi(a)unito.it) or Carlo Collari (carlo.collari(a)dm.unipi.it). The workshop also includes a poster session. Those interested in presenting a poster should send an email to crm(a)sns.it, including title and abstract, for the evaluation by the Scientific Committee. For more information visit the website: http://www.crm.sns.it/event/523/ Looking forward to seeing you in Pisa. The organisers, Luigi Caputi, Carlo Collari, and Paolo Lisca

---------- Forwarded message --------- Da: wagner(a)imj-prg.fr <wagner(a)imj-prg.fr> Date: Sab 2 Set 2023, 10:00 Subject: [gdrtresses] WinterBraids XIII To: gdrtresses(a)listes.math.cnrs.fr <gdrtresses(a)listes.math.cnrs.fr> ***************************************************** Winterbraids XIII --- second announcement School on braids and low-dimensional topology Montpellier, February 6-9 2024 ****************************************************** Winterbraids XIII is the 13th edition of an itinerant school on braids and low-dimensional topology, that will be held at Institut Montpelliérain Alexander Grothendieck (Montpellier) from February 6th to 9th, 2024. The school consists on three 3-hours mini-courses and a special lecture: * Asilata Bapat (ANU, Australia): Braids and stability conditions * Marco Golla (Nantes, France): Surfaces in 4-manifolds * Bram Petri (Sorbonne, France): Probabilistic methods in low-dimensional hyperbolic geometry * Vincent Pilaud (Polytechnique, France): Combinatorial geometry These will be completed by short talks and a poster session devoted to student presentations (not necessarily focused on braids or their generalizations). The school will be mainly supported by the Institut Montpelliérain Alexander Grothendieck, the Université de Montpellier, the GDR Tresses, the ETH Zürich, and the European Commission. The school will start on Tuesday morning and will end on Friday at noon. Registrations are avaible online: (deadline 15 november) https://winterbraids-xiii.sciencesconf.org/ For any queries, please contact the organizers at winterbraids-xiii(a)sciencesconf.org Organizers: Berenice Delcroix-Oger (Université de Montpellier) Peter Feller (ETH, Zurich) Vincent Florens (Université de Pau et des pays de l'Adour) Hoel Queffelec (Université de Montpellier)
