In this talk I will discuss foliations with positive tangent sheaf, with focus on those with ample anti-canonical class. I will present some results and techniques developed in a series of joint works with Stéphane Druel.   ICTP ICTP pio@ictp.it 7 Jun 2017

Europe/Rome 2017-06-19 08:00:00 2017-07-07 22:00:00 ICTP-EAUMP School on Modern Functional Analysis | (smr 3133) The summer school is intended to provide a thorough introduction to various topics in functional analysis, from introductory to more advanced, and with a particular focus on functional analytic methods used in current research. The two introductory courses in the first week cover some of the fundamentals of functional analysis and of operator theory, before two more advanced courses in the second week will introduce ideas which establish a link between the methods of classical functional analysis and the modern theory of partial differential equations. Finally, the two courses in week three will expose participants to some more advanced topics which tie together the areas of functional analysis, differential equations and geometry. Each of the courses will consist of a series of lectures and accompanying classes, which are intended to give participants an opportunity to deepen their understanding of the material introduced in the lectures. All of the lecture courses will be delivered by internationally recognised researchers in analysis. In the final week of the summer school, participants will have a chance to work independently on a small topic of their choice. COURSES Week 1, 19-23 June - Introductory courses Course 1: An introduction to function spaces Lecturer: Dr Lassi Paunonen (Tampere, Finland) Description: An overview of the basic theory of Banach and Hilbert spaces, with a focus on function spaces which play a part in modern applications of functional analysis Syllabus: Overview of basic properties of Banach and Hilbert spaces (completeness, separability, reflexivity, etc), some fundamental theorems in functional analysis (e.g. the Riesz Representation theorem and the Hahn-Banach theorem), examples with relevance to modern applications of functional analysis (Sobolev spaces, Bergman spaces, Hardy spaces etc) Course 2: An introduction to operator theory Lecturer: Prof. Charles Batty (Oxford, UK) Description: An overview of some of the central theorems on linear operators between normed vector spaces, touching on the theory of unbounded linear operators Syllabus: Overview of the basic theory of bounded linear operators between Banach spaces, spectral theory, some fundamental results in classical operator theory (uniform boundedness theorem, closed graph theorem, open mapping theorem, inverse mapping theorem), introductory material on the theory of closed unbounded operators (as time permits) Week 2, 26-30 June - Advanced courses Course 3: Advanced operator theory Lecturer: Dr David Seifert (Oxford, UK) Description: An overview of some more advanced topics in operator theory, making the connection with modern PDE theory Syllabus: Compactness in normed vector spaces, compact operators (characterisation, properties, spectral theory, examples), operators with closed range, the closed range theorem, Fredholm theory (Fredholm index, Fredholm alternative, perturbation results), existence and uniqueness for simple elliptic PDEs via the Fredholm alternative Course 4: The theory of operator semigroups and their applications Lecturer: Dr Sachi Srivastava (University of Delhi) Description: An introduction to the theory of strongly continuous operator semigroups and their applications Syllabus: C0-semigroups, infinitesimal generators, spectral theory of generators, Lumer-Phillips theorem, Hille-Yosida theorem, examples, abstract Cauchy problems, mild solutions, applications to simple PDEs (heat equation, wave equation) and quantum systems Week 3, 3-7 July - Modern applications of functional analysis Course 5: The Laplacian on a Riemannian manifold Lecturers: Prof Claudio Arezzo and Dr Luca Di Cerbo (ICTP) Syllabus: Basic theory of differential and Riemannian manifolds.

There will be ample opportunities for interaction and discussion amongst participants of all levels of experience.   The workshop is organized in conjunction with a school in Hyperbolic Dynamics which will be held on 12-16 June 2017 at the Centro di Ricerca Matematica Ennio de Giorgi, Pisa, with mini-courses by D. Dolgopyat (Maryland), S. Luzzatto (ICTP), Y. Pesin (Penn State), F. Rodriguez-Hertz (Penn State) and some invited seminars. Details can be found on the website of the school at: http://crm.sns.it/event/410/  Registration, participation and funding for the two events are independent of each other.   Topics: Uniform and nonuniform hyperbolicity Partial hyperbolicity Lyapunov exponents Ergodic Theory Thermodynamical formalism Dimension Theory Statistical properties of deterministic dynamical systems Decay of correlations Markov extensions and structures Preliminary list of Speakers: Aaron Brown Leonid Bunimovich Keith Burns Jerome Buzzi Manfred Denker Dmitry Dolgopyat Andrey Gogolev Mike Hochman Huyi Hu Michael Jakobson Anatole Katok Svetlana Katok Konstantin Khanin Carlangelo Liverani Stefano Luzzatto Stefano Marmi Mark Pollicott Federico Rodriguez-Hertz Omri Sarig Jeorg Schmeling Samuel Senti Mike Shub Domokos Szasz Sandro Vaienti Amie Wilkinson Ke Zhang ICTP ICTP pio@ictp.it 19 Jun 2017 - 23 Jun 2017

Europe/Rome 2017-07-19 08:00:00 2017-07-22 22:00:00 Mediterranean Youth Mathematical Championship 2017 (Roma Tre University, Rome) - (smr 3171) An initiative to encourage Mediterranean youth, both male and female, to develop an interest in Mathematics, a discipline which has been of great importance for the growth of the cultural community of the Mediterranean, with its many nations and religions. Working language of the championship: English Some 20 teams involved, one for each of the Mediterranean countries. Each team consisting of 4 people, 2 boys and 2 girls, presently attending the last three years of high school (and at most nineteen years old). Each team selected by appropriate local entities (e.g., the local entities in charge of the IMO). For more information on MYMC 2017: http://www.mymc.it/MYMC2017/index.htm Program: July 19, 2017 - Arrival in Rome July 20, 2017 - Opening ceremony and contest on the premises of Roma Tre university July 21, 2017 - Awards ceremony and visit of Rome July 22, 2017 - Departure from Rome Contest operating methods: July 20 in the morning 1. A common list of problems for all teams 2. Preliminary ranking of the teams according to their score July 20 in the afternoon (direct clashes) 1. First round – direct clashes between 1st and 2nd ranked teams, 3rd and 4th ranked teams, 5th and 6th ranked teams, etc. 2. Second round – direct clashes between randomly coupled teams 3. Each direct clash carries some points to the teams 4. The points accumulated in the afternoon are added to those scored in the morning. Description of a direct clash Each team receives two lists of problems and decides which one to keep, the other being passed to the opponent. Thus every team has two lists of problems to solve in a fixed amount of time. The winner is the team able to solve more problems (hence a tie is possible). July 20 in the afternoon (final problem) A common problem is given to each team, to be solved in at most 10 minutes. The team which first provides the correct answer is awarded 3.5 points; all the other teams providing a correct answer are awarded 1 point. If a team provides an incorrect answer, it is awarded 0 points. If a team does not provide an answer, it is awarded 0.5 points. The points awarded are added to those already accumulated. The final ranking of the MYMC is decided by the Jury based on the final score obtained by the various teams, at the conclusion of the competitions described above.
