Seminario di Combinatoria, Teoria di Lie e Topologia - 3 Marzo 2022 - Nicoletta Cantarini
by Francesco Sala 02 Mar '22

02 Mar '22

Carə tuttə, Vi scrivo per annunciarvi che domani vi sarà un seminario per il ciclo di seminari "Seminario di Combinatoria, Teoria di Lie e Topologia” di Pisa. Il seminario si svolgerà in Aula Riunioni dalle 15 alle 16. L'oratrice è Nicoletta Cantarini (Università di Bologna). — Titolo: Verma modules for the Lie superalgebra E(5,10) Abstract: in this talk we will describe the construction of the so-called finite Verma modules for Z-graded Lie superalgebras and study the finite Verma modules over the exceptional linearly compact Lie superalgebra E(5,10). This is done through the classification of singular vectors. We will show that the corresponding morphisms of Verma modules can be arranged in an infinite number of bilateral infinite complexes which can be viewed as "exceptional" de Rham complexes for E(5,10). — Vi prego di inoltrare questo messaggio a tuttə coloro che ritenete possano essere interessatə. Sperando di vedervi numerosə, vi mando i miei saluti, A presto, Francesco

seminario
by Paolo Lisca 23 Feb '22

23 Feb '22

Buongiorno, inoltro avviso di seminario. Paolo Lisca --------------- Data e ora: giovedì 18 gennaio ore 15 Speaker: Carlo Collari (Università di Pisa) Titolo: Omologia Multipath e poset dei multi-cammini. Title: Multipath homology and the path poset. Abstract: The aim of this talk is to present some homology theories for graphs (and, in particular, multipath homology), describe their mutual relationship, and see how these theories are connected with other homology theories (i.e. homology theories for knots and algebras). We start by describing some classical theories for graphs. Then, we will focus on the construction, due to Helme-Guizon and Rong, of chromatic homology. This theory categorifies the chromatic polynomial of graphs, and its construction is based on Khovanov homology. In particular, we will present a result due to J. Przytycki, which relates Khovanov homology, chromatic homology, and Hochschild homology. Afterwards, we will describe Turner and Wagner's approach to the "extension" of chromatic homology to oriented graphs while preserving an analogue of Przytycki's result. Finally, we will define multipath homology and compare it with Turner-Wagner homology. In the last part of the talk, time permitting, we will give a topological description of the path poset, which is a key ingredient in the definition of Turner-Wagner and multipath homologies. This talk is based on joint work with L. Caputi (University of Aberdeen) and S. Di Trani (Sapienza Università di Roma). -------------------- Il seminario avrà luogo nella sala virtuale: https://teams.microsoft.com/l/meetup-join/19%3ameeting_MTgxNjUyYTEtNTljOC00… [https://statics.teams.cdn.office.net/hashedassets-launcher/favicon/favicon-…]<https://teams.microsoft.com/l/meetup-join/19%3ameeting_MTgxNjUyYTEtNTljOC00…> Join conversation<https://teams.microsoft.com/l/meetup-join/19%3ameeting_MTgxNjUyYTEtNTljOC00…> teams.microsoft.com

Seminario Leone Slavich
by Bruno Martelli 03 Feb '22

03 Feb '22

Buondì, Annuncio un seminario di Leone Slavich che si terrà a Pavia, ma seguibile anche on line su Zoom (link in fondo alla mail) Bruno ---- Speaker: Leone Slavich Orario: mercoledì 9 febbraio alle 14:30 Titolo: Totally geodesic immersions of hyperbolic manifolds Abstract: The study of totally geodesic immersions between (complete, finite-volume) hyperbolic manifolds is a classical problem in the field of hyperbolic geometry. There are two main approaches to this problem which often interplay with each other: 1) Given a hyperbolic manifold N, determine the hyperbolic manifolds in which N can be immersed geodesically; 2) Given a hyperbolic manifold, determine its totally geodesic immersed submanifolds. We will show how it is possible to build totally geodesic immersed submanifolds in a hyperbolic manifold M using finite subgroups in the commensurator of M. We will call the subspaces arising from this construction "finite centralise subspaces" (or fc-subspaces) and use them to provide an arithmeticity criterion in terms of their finiteness/non-finiteness. In the case of arithmetic hyperbolic manifolds we will show how to characterise all totally geodesic immersions through the analysis of certain algebraic invariants: the adjoint trace field (which is an algebraic number field) and the ambient group (an algebraic group defined over the adjoint trace field). Sara' possibile seguire anche il seminario online al seguente link zoom: Join Zoom Meeting https://us02web.zoom.us/j/83228812062 Meeting ID: 832 2881 2062 ...

Inoltro annuncio di convegno. Paolo Lisca ________________________________ Da: Paul Seidel <pseidel(a)mit.edu> Inviato: mercoledì 5 gennaio 2022 22:36 Oggetto: PLEASE DISTRIBUTE: Research conference "Frontiers in Geometry and Topology", ICTP, Trieste (Italy), August 8-12, 2022; APPLICATIONS OPEN NOW, DEADLINE FEBRUARY 28, 2022 We are delighted to announce this conference, to be held at ICTP, Trieste (Italy), August 8-12, 2022. The conference will cover several areas of current research, including low-dimensional topology, gauge theory, and Floer homology in all its flavors. It is partly intended to celebrate the mathematical contributions of Tomasz Mrowka. The conference will be preceded by a summer school for graduate students (the week before). Speakers: (* = to be confirmed) David Gabai, Lothar Goettsche, Larry Guth, Jen Hom, Cole Hugelmeyer, *Peter Kronheimer, Francesco Lin, Robert Lipshitz, Paolo Lisca, Ciprian Manolescu, Gordana Matic, Rafe Mazzeo, Maggie Miller, Emmy Murphy, *John Pardon, Lisa Piccirillo, Juanita Pinzon Caicedo, Jake Rasmussen, *Daniel Ruberman, Andras Stipsicz, Zoltan Szabo, *Cliff Taubes, Donghao Wang, Claudius Zibrowius. Applications are open now, and the deadline is FEBRUARY 28, 2022. You can find the application page linked to from the main event web page http://indico.ictp.it/event/9706/ A bit of practical information (some of which is still preliminary): WHO CAN APPLY? The application process is open, but due to space limitations at ICTP, we may have to be selective. Prospective participants will be informed of the outcome of the application as soon as possible. HOW ABOUT COVID AND REMOTE PARTICIPATION? We encourage in-person participation, but in view of current uncertainties, the conference is designed as hybrid, and allows remote participation if necessary. Note that remote participants have to go through the same application process as in-person ones. WHERE WILL PARTICIPANTS STAY? ICTP has on-campus housingthat participants can book at a reasonable price. Alternatively, ICTP will be able to assist with finding a hotel in the town of Trieste. HOW ABOUT REIMBURSEMENT FOR HOUSING AND TRAVEL? Unfortunately, for most conference participants, we will NOT beable to provide any kind of reimbursement. One exception are participants from developing countries, for whom ICTP will contribute a limited amount of resources (this is part of ICTP's mission of encouraging the worldwide development of mathematics and physics). The other exception are graduate students staying on from the summer school, where we have a small amount of funding for travel expenses from the Clay Mathematics Institute. We have a pending application for funding from the National Science Foundation, which if approved would provide additional resources for a small number of US-based graduate students and postdocs.) Organizing committee: Paul Feehan, Lenny Ng, Peter Ozsvath, Yongbin Ruan, Paul Seidel
