14 Dec '23

---------- 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).

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

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
