Seminari di Geometria 13/4
by Filippo Bianchi 13 Apr '23

13 Apr '23

Care tutte e cari tutti, Vi ricordo che domani alle 11 in Aula Seminari si terrà il seminario di Raphael Zentner (Durham University) dal titolo "SL(2,C)-character varieties of knots and maps of degree 1 – Raphael Zentner (Durham University)", di cui riporto l'abstract We ask to what extend the SL(2,C)-character variety of the fundamental group of the complement of a knot in S^3 determines the knot. Our methods use results from group theory, classical 3-manifold topology, but also geometric input in two ways: the geometrisation theorem for 3-manifolds, and instanton gauge theory. In particular this is connected to SU(2)-character varieties of two-component links, a topic where much less is known than in the case of knots. This is joint work with Michel Boileau, Teruaki Kitano, and Steven Sivek. Vi aspettiamo! Buona serata, Alice, Filippo e Giuseppe

Seminario di geometria oggi
by Filippo Bianchi 06 Apr '23

06 Apr '23

Buonasera, Scusandoci per il poco preavviso, annunciamo il seminario di geometria di oggi. Ricordiamo che l'elenco completo dei seminari si trova a questa pagina<https://www.dm.unipi.it/categoria-evento/geometry-seminar/>. A presto, Filippo, Alice e Giuseppe ----- 06-Apr-2023 - 11:00 Sala Seminari (Dip. Matematica) Instanton Floer homology of almost-rational plumbings Antonio Alfieri UQAM Plumbed three-manifolds are those three-manifolds that can be be realized as links of isolated complex surface singularities. Inspired by Heegaard Floer theory Nemethi introduced a combinatorial invariant of complex surface singularities (lattice cohomology) that was recently proved to be is isomorphic to Heegaard Floer homology. I will give an introduction to lattice cohomology, and expose some work in collaboration with John Baldwin, Irving Dai, and Steven Sivek showing that the lattice cohomology of an almost-rational singularity is isomorphic to the framed Instanton Floer homology of its link.

---------- Forwarded message --------- Da: Maria Rita CASALI <mariarita.casali(a)unimore.it> Date: Mer 5 Apr 2023, 19:08 Subject: Conference "Geometric Topology, Art, and Science" in Modena and Reggio Emilia (June 8-10, 2023) To: Maria Rita CASALI <casali(a)unimore.it> Dear Colleagues, we are pleased to announce the conference *Geometric Topology, Art, and Science* to be held in Reggio Emilia (Italy) on June 9-10, 2023, with a pre-meeting in Modena on June 8, 2023. The conference is jointly organised by the Department of Physics, Informatics and Mathematics (FIM) and the Department of Sciences and Methods for Engineering (DISMI) of the University of Modena and Reggio Emilia, on the occasion of 70th birthday of Luigi Grasselli, full professor of Geometry at DISMI. The conference focuses on recent advances in Geometric Topology, with a particular attention to combinatorial descriptions of 3- and 4-manifolds (branched coverings, knots and braids, trisections, colored graphs, etc…), as well as to the interactions with other disciplines, ranging from physics (with the theory of *random tensors*) to geometrical aspects in classical and contemporary art. Confirmed speakers include • Bruno Benedetti (University of Miami) • Alessia Cattabriga (University of Bologna) • Antonio Costa (UNED, Madrid) • Massimo Ferri (University of Bologna) • Luca Lionni (University of Heidelberg) • Josè Maria Montesinos Amilibia (Real Academia de Ciencias Exactas, Físicas y Naturales de España) • Daniele Zuddas (University of Trieste) The conference will also host a poster session. During the preliminary event (which will take place in Modena on June 8 afternoon, at the Department FIM) young researchers who intend to present a poster will be invited to give short talks on their own research. In this occasion, we foresee ample room for discussion and informal interaction in order to facilitate the scientific exchange between participants. More information and the detailed programme can be found at the webpage https://sites.google.com/view/gras70/ Participants are requested to register at https://sites.google.com/view/gras70/registration and fill the related form. No registration fee is required. The deadline for talk/poster submission and registration is April 30, 2023. A limited amount of funding is available for early-career researchers intending to participate in the session of talks and to present posters. Application for funding can be made through the registration form. Finally, we would like to ask you to forward the announcement to any of your colleagues who might be interested. We look forward to meeting you at the conference. *Maria Rita Casali* *(on behalf of the Organisers)*

A presto, Filippo, Alice e Giuseppe ----- 30-Mar-2023 - 11:00 Sala Seminari (Dip. Matematica) Linear programming for hyperbolic surfaces Bram Petri IMJ Paris I will speak about extremal problems in the (spectral) geometry of hyperbolic surfaces and how linear programming methods based on the Selberg trace formula can help. I will not assume any familiarity with hyperbolic geometry or the Selberg trace formula. This is joint work with Maxime Fortier Bourque.

Inoltro info su summer school Bruno ---------- Forwarded message --------- From: Erwan Brugallé <Erwan.Brugalle(a)math.cnrs.fr> Date: Mon, Mar 27, 2023 at 7:32 AM Subject: Summer school "Involutions in algebraic geometry and gauge theory", Nantes Université, 2023 May 30-June 2 To: Marco GOLLA <Marco.Golla(a)univ-nantes.fr>, Erwan Brugallé < Erwan.Brugalle(a)math.cnrs.fr> ################## # Second announcement ################## Dear colleagues, We are organising a summer school on "Involutions in algebraic geometry and gauge theory" at the University of Nantes (May 30-June 2, 2023). There will be two mini-courses, one by Matilde Manzaroli (Tübingen University) on real algebraic curves and one by Christopher Scaduto (University of Miami) on 4-manifolds and involutions. We expect to have some contributed talks by young participants. Master students are particularly encouraged to apply. The schedule will be pretty light, in order to allow the participants ample time to work on the material covered in the lectures. Some familiarity with knot theory and with (very basic) complex projective geometry will be assumed. You can find more information on the webpage of the school: https://es.sonicurlprotection-fra.com/click?PV=2&MSGID=20230327053200063942… The registration page is here: https://es.sonicurlprotection-fra.com/click?PV=2&MSGID=20230327053200063942… and the registration deadline is March 30, 2022. Could you pass this information on to any PhD student/postdoc/motivated Master student who might be interested in attending? Limited funding is available for Master students and for contributed speakers. However, should funding be an insurmountable issue, do ask them to get in touch (math.summer-school (at) univ-nantes.fr). Thank you! The organisers, Erwan Brugallé and Marco Golla
