by Bruno Martelli 15 Jan '24

15 Jan '24

Ricevo ed inoltro, Bruno ---- Dear all, This is a reminder that registration for the 12th edition of Young Geometric Group Theory (YGGT XII) is currently open. The registration form and instructions can be found on the conference website: https://sites.google.com/view/yggt2024. The closing date is *19th January 2024*. We would encourage you to pass this information on to any PhD student, masters student, or postdoc who might be interested in attending, but who might not be on this mailing list. YGGT is a series of annual conferences which were initiated in 2012, with the aim of allowing early-career researchers in geometric group theory from all over the world to meet, forge new connections and, of course, learn more about geometric group theory. The 12th edition will take place *from the 8th to 12th of April 2024* in Bristol, UK. Best regards, Alice Kerr, Davide Spriano, Rylee Alanza Lyman, Vladimir Vankov

I: 4-year PhD position in Differential Topology in Utrecht (Netherlands)
by Paolo Lisca 25 Dec '23

25 Dec '23

Da: Pino Gomez, A. del (Alvaro) <a.delpinogomez(a)uu.nl> Inviato: lunedì 18 dicembre 2023 18:00 A: Alvaro del Pino Gómez Oggetto: 4-year PhD position in Differential Topology in Utrecht (Netherlands) Dear friends and colleagues, I am advertising a 4-year PhD position in Differential Topology/Geometry in Utrecht University (Netherlands), to start no later than September 2024. The research project will deal with the classification of geometric structures up to homotopy. More concretely, it will focus on the use of h-principle techniques to classify tangent distributions (although there is room to adapt the concrete goals to the taste of the PhD candidate). The math department in Utrecht is very nice and lively. A list of members can be found here: https://utrechtgeometrycentre.nl/members/ The candidate will interact mostly with our Algebraic Topology and Differential Geometry groups. If this sounds attractive to you, you can apply here: https://www.uu.nl/en/organisation/working-at-utrecht-university/jobs/phd-po… The deadline is 8th January 2024. Moreover, feel free to forward this application to potential applicants. All the best! Álvaro del Pino

Seminario di geometria 21/12
by Filippo Bianchi 19 Dec '23

19 Dec '23

Carə tuttə, Giovedì 21 Dicembre alle 14.30 in Aula Seminari si terrà il seminario di Marco De Renzi (Université de Montpellier) dal titolo "Algebraic presentation of cobordisms and TQFTs". Di seguito l'abstract. It has long been known that the category of 2-dimensional cobordisms is freely generated by a commutative Frobenius algebra, the circle. This result allows for a complete classification of TQFTs (Topological Quantum Field Theories) in dimension 2. In this talk I will discuss similar algebraic presentations in dimension 3 and 4 due to Bobtcheva and Piergallini. In both cases, the fundamental algebraic structures are provided by certain Hopf algebras called BPH algebras. I will also present examples of such algebras and the TQFTs they induce. This is a joint work with A. Beliakova, I. Bobtcheva, and R. Piergallini. Ci troveremo alle 13 in atrio per andare a pranzo. 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 --------- Da: Giuseppe Pipoli <giuseppe.pipoli(a)univaq.it> Date: Gio 14 Dic 2023, 17:33 Subject: Announcement post doc position in L'Aquila To: Dear Colleague, We are pleased to announce a one-year postdoctoral position (Assegno di Ricerca) in L'Aquila. The position is funded by the PRIN project "Differential-geometric Aspects of Manifolds via Global Analysis." The salary is approximately €1450 after taxes, with the possibility of renewal for a second year. The research will focus on Riemannian and Complex Geometry and Geometric Analysis. Topics of particular interest include the geometry of Riemannian submanifolds whose curvature satisfies specific equations or geometric properties, their evolution through geometric flows, geometric flows of Riemannian and Complex manifolds, classifications of geometric structures on real and complex manifolds, and isoperimetric inequalities on manifolds and Riemannian submanifolds. The call is available at - * https://bandi.miur.it/bandi.php/public/fellowship/id_fellow/250798 <https://bandi.miur.it/bandi.php/public/fellowship/id_fellow/250798>* - *https://www.univaq.it/include/utilities/blob.php?table=assegni_ricerca&id=892&item=bando <https://www.univaq.it/include/utilities/blob.php?table=assegni_ricerca&id=8…>* You can apply online at *https://pica.cineca.it/univaq/disim-2023-ar-11/ <https://pica.cineca.it/univaq/disim-2023-ar-11/>* I would be grateful if you would spread this message to all potentially interested people.

Seminario Baby Geometri 13/12
by Giovanni Framba 12 Dec '23

12 Dec '23

Carə tuttə, Vi invitiamo al seminario dei Baby Geometri di questa settimana: Mercoledì 13 Dicembre 2023, alle ore 14:30 Presso l’Aula Riunioni (Dipartimento di Matematica) Gemma Di Petrillo (Università di Trento) terrà un seminario dal titolo: Quaternions and isometries of the hyperbolic 5-space di cui riporto l'abstract: It is a well-known fact that the group of orientation-preserving isometries of the hyperbolic n-space is isomorphic to the matrix group SO^+(n,1). When n=2 and n=3, these groups have a "friendlier" description as the 2x2 matrix groups PSL(2,R) and PSL(2,C). By identifying R^4 with the quaternion algebra H, we will see that something similar happens in the n=5 case: more precisely, we will show that SO^+(5,1) is isomorphic to PSL(2,H) - the space of 2x2 quaternionic matrices with Dieudonné determinant equal to 1. At the end of the talk, I will give an idea on how these results can be applied to try and understand deformations of complete hyperbolic 3-manifolds (with finite volume) in the 5-dimensional hyperbolic space. This is based on a joint work with Bruno Martelli. Vi ricordiamo infine che potrete trovare informazioni sui prossimi seminari sul nostro sito https://sites.google.com/view/babygeometri [https://lh5.googleusercontent.com/CtqlqJpO6ZXiyBenfbgtGLv_DkKlGOpGCBByGwXOD…]<https://sites.google.com/view/babygeometri> Seminari dei Baby Geometri<https://sites.google.com/view/babygeometri> I Baby Geometri sono un ciclo di seminari di Geometria e Topologia organizzati dai dottorandi dell'Università di Pisa (UNIPI) e perfezionandi della Scuola Normale Superiore di Pisa (SNS). Si tratta di seminari informali su argomenti classici oppure tematiche di ricerca. Poiché il pubblico è sites.google.com . Tutte le persone interessate sono invitate a partecipare.

Seminario di Geometria 7/12
by Filippo Bianchi 06 Dec '23

06 Dec '23

Carə tuttə, Giovedì 7 Dicembre alle 14.30 in Aula Seminari si terrà il seminario di Carlo Collari (Università di Pisa) dal titolo "Strongly Invertible Legendrian Links". Di seguito l'abstract. In this talk I will introduce strongly invertible Legendrian links in the standard contact three-dimensional space. After a short presentation of the equivariant analogues of well-known theorems for both strongly invertible and Legendrian links, e.g. the equivariant Legendrian Reidemeister theorem, I will introduce the maximal equivariant Thurston-Bennequin number. I will conclude the talk discussing some experimental results and conjectures concerning the maximal equivariant Thurston-Bennequin number. This is joint work with Paolo Lisca (Università di Pisa). Ci troveremo alle 13 in atrio per andare a pranzo. 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
