Europe/Rome 2020-06-23 16:00:00 2020-06-23 17:00:00 Basic notions seminar on mean curvature flow of closed hypersurfaces Information on how to register will follow soon. Abstract: The seminar will start with the definition of what is mean curvature flow of a closed hypersurface, illustrated with some basic examples. Next, I will recall the variational nature of the flow and some of the main well-known results, such as Grayson theorem for the evolution of plane curves, and Huisken convexity preserving theorem. At the end of the seminar, some more advanced topics will be mentioned. Zoom Meeting ICTP pio@ictp.it 23 Jun 2020

Europe/Rome 2020-06-24 17:00:00 2020-06-24 18:00:00 Ergodic and thermodynamic properties of pseudo-Anosov diffeomorphisms Abstract: We discuss the thermodynamic and ergodic properties of a smooth realization of pseudo-Anosov surface homeomorphisms. In this realization, pseudo-Anosov map is uniformly hyperbolic outside of a neighborhood of a set of singularities, and the trajectories are slowed down so the differential is the identity at the singularities. Using Young towers, we prove existence and uniqueness of equilibrium measures for geometric $t$-potentials. This family of equilibrium measures includes a unique smooth SRB measure and a measure of maximal entropy, the latter of which has exponential decay of correlations and the Central Limit Theorem.

Our results cover all compact surfaces of genus at least 2 without conjugate points. This is based on a join work with Vaughn Climenhaga and Gerhard Knieper. Zoom Meeting ICTP pio@ictp.it 2 Jul 2020

Europe/Rome 2020-06-29 08:00:00 2020-07-03 22:00:00 Complex Analysis, Geometry and Dynamics ECM-ICTP 2020 * CANCELLED * | (smr 3457) Note: ICTP has suspended all educational activities from 24 February up to 26 June as precautionary measures due to COVID-19; more details at https://www.ictp.it/about-ictp/media-centre/news/2020/2/ictp_suspend_activities.aspx The goal is to bring together leading researchers worldwide in complex analysis, geometry, and dynamics, with the aim of enhanced future collaboration. These fields are strongly interrelated, and in order to be able to solve deep challenging problems it is becoming necessary to pursue synergies among them to a bigger degree than in the past. Topics: Holomorphic approximation theory L2 techniques, plurisubharmonic functions, complex pluripotential theory Complex dynamics in higher dimensions Holomorphic directed systems, contact systems Applications of complex analysis to minimal surfaces Flexibility versus rigidity in complex geometry Cauchy-Riemann geometry Monge-Ampėre equations and Kähler manifolds There have been major recent advances in all these topics which the speakers will report on. It is becoming increasingly evident that a deeper level of cooperation will be needed for further progress. Speakers: A. ALARCÓN, University of Granada, Spain D.

It brings together well-established experts and young researchers in representation theory and in allied fields where representation theory is applied. The first week will consist of a workshop with six lecture series, including introductory talks and on topics of particular current interest, such  as recent links to both topological data analysis and to mathematical physics. One of the lecture series will be devoted to the mathematical heritage of Ragnar Buchweitz. The second week will be a conference with invited speakers in addition to contributed talks, both in plenary and in parallel sessions. Topics: Representation theory of algebras and its applications, including: -Topological Data Analysis -Cluster algebras -Non-commutative algebraic geometry -Modular representation theory.

Europe/Rome 2020-08-03 08:00:00 2020-08-14 22:00:00 EAUMP-ICTP School: Topics in Concrete Mathematics | (smr 3465). CANCELLED DUE TO THE COVID19 PANDEMIC THIS SCHOOL HAS BEEN CANCELLED. --------------------- Original text purpose of the School ---------------------- This School will be held at the ICTP-East African Institute for Fundamental Research [EAIFR] in Kigali, Rwanda; it will offer students concrete and effective mathematical tools from algebra, group theory and geometry that can be applied to any scientific field. Description of Courses:   Advanced linear algebra This goes beyond a first course on the subject. Topics like Jordan normal form will be studied as well as bilinear forms, multilinear forms and tensor products;  Groups, Counting and FFT We start with group theory via rotations in 3d space; this will be used in Pólya counting problems. We then moves on to character theory culminating in fast Fourier transform;  Introduction to Lie Algebras The course introduces Lie algebras and aims towards of the classification of semisimple Lie algebras  which is widely considered one of the most elegant results in mathematics;  Modular forms The course introduces modular forms. We will study many concrete examples, like the Eisenstein series, from which we will construct the finite dimensional spaces of modular forms of any weight.     Kigali - Rwanda ICTP pio@ictp.it 3 Aug 2020 - 14 Aug 2020
