Europe/Rome The Eastern Africa Universities Mathematics Programme (EAUMP) courtesy of the International Science Programme (ISP) of Sweden; jointly with ICTP, Trieste, Italy; Sida, CIMPA, DAAD, LMS/AMMSI, COMPOSITIO is organizing a three weeks summer School on Algebraic Topology and its Applications to be held at Makerere University, Kampala, Uganda from 15th July to 30th July, 2019. It is intended that the School will take the audience comprising young academic staff members and advanced graduate students (M.Sc, Ph.D and Postdoctoral Students) of Mathematics from the Eastern African region and beyond. The school is the next one in a series of schools organized under the Eastern African Universities Mathematics Programme (EAUMP). The most recent EAUMP schools were organized in 2015 at Makerere University, Uganda, on Experimental Pure Mathematics; in 2016 at the University of Rwanda on Number Theory; in 2017 at the University of Nairobi on Modern Functional Analysis; and in 2018 at the University of Dar es Salaam on Homological methods in Algebra and Geometry. All the schools are within one of the main aims of EAUMP which is to improve the pure mathematics in the region. The member Universities of the EAUMP are University of Dar es Salaam, Tanzania; University of Nairobi, Kenya; University of Zambia, Zambia; Makerere University, Uganda; University of Rwanda, Rwanda. GOALS OF THE SCHOOL To introduce participants to current trends in Algebraic Topology and its applications, including knot theory and Topological Data Science, and provide research topics for masters and PhD studies. To provide a forum for African mathematicians to interact, exchange ideas and initiate collaborations. Identify talented students for possible PhD programs. To produce digital lecture material for dissemination, which contributes to the training of master students in the Eastern Africa region. STURCTURE AND PROGRAMME As in the years 2013-2017, participants will be asked to submit mini-projects on the material studied at the School, with the best submissions receiving prizes/awards. They will work on their projects after the end of the School and will submit them during the third week of the school. Here is the detailed course plan for the School. Week 1: Introductory courses Course 1: Introductory Topology Lecturer: Venuste Nyagahakwa (University of Rwanda) Description: This course will introduce the basic ideas of topology, starting with an abstract definition of topological space, and treating many examples. Course 2: The Fundamental Group Lecturer: Jean-Baptiste Gatsinzi (Botswana Institute of Science and Technology) Description: The fundamental group is a basic but key algebraic invariant of a topological space. This course will define this group and give some interesting examples of how to compute it. Course 3: Introduction to knot theory Lecturer: Balazs Szendroi (University of Oxford) Description: A knot is a tangled piece of rope in the three dimensional space, with the two loose ends glued together. Knot theory asks questions such as: can this knot be untangled by continuously deforming the rope? Are there ways to tell two knots apart? This course will discuss these motivating questions and present some ideas how to solve them. Week 2: Advanced courses Course 3: Manifolds Lecturer: Claudia Scheimbauer (NTNU, Trondheim) Description: Manifolds provide a very interesting class of examples of topological spaces, of great interest in applications to geometry, physics and elsewhere. This course will introduce this notion with many examples, mainly from dimensions 1, 2 and 3. Course 4: Topological Data Analysis Lecturer: Ulrike Tillmann (University of Oxford) Description: Topological data analysis is a recent and fast-growing field providing a set of new topological and geometric tools to infer global features from complex data. This course will give an introduction to this circle of ideas. SCHOOL PARTICIPATION Online application form is available at http://indico.ictp.it/event/8699/, and will close on 28th April, 2019.

Week 1: Please click on the link "Apply here" on the left hand-side column Week 2: Please apply at: http://indico.ictp.it/event/8900/ DEADLINE for requesting participation for both weeks: 15 MAY 2019 ========================================================== Organizers: A. Agrachev, SISSA, Trieste A. Bufetov, Marseille & Steklov Institute T. Grava, SISSA & Bristol A. Guionnet, ENS Lyon S. Kuksin, Paris & Shandong University Local Organizer: S. Luzzatto, ICTP, Trieste The topics to be discussed at the activity are at the forefront of current research in Random Matrix Theory, Point Processes, Dynamical Systems and Control Theory. One of the main goals of the School and Workshop is to bring this material to both established and young mathematicians from all developing countries. Mini courses will be given as well as more advanced reserach seminars. The activity will be organized as two thematic weeks on interrelated topics. Each week will consist of one or two mini courses and some seminar speakers. Week 1: Mixing and Control Mixing and control central topic is the study, with the help of the mathematical control theory, of ergodic and mixing properties of dynamical systems stochastically perturbed by a very degenerate noise. This concerns the systems governed by nonlinear PDEs and ODEs. We also plan to discuss mathematical aspects of the non-equilibrium statistical physics and some other topics. Week 2: Random Matrix Theory and Point Processes The second week will focus on point processes arising in the study of random matrices such as determinantal point processes. These point processes satisfy the Kolmogorov 0-1 Law and the Central Limit Theorem of Soshnikov, are rigid in the sense of Ghosh and Peres and obey an analogue of the De Finetti Theorem. Palm-Khintchine theory for our point processs will be emphasized, as well as the connection with the theory of integrable systems. Numerous open problems will be discussed, in particular, those related to pfaffian point processes. Topics: Point process; Random matrices; Integrable probability; Integrable systems; Mixing; Stationary measure; Markov systems; Nonholonomic constraints; Controllability; Lecturers: A.

**DEADLINE: 15/05/2019**

Europe/Rome Ergodic theory has its origins in the the work of L. Boltzmann on the kinetic theory of gases. The closely related field of dynamical systems has a much older origin, going back at least to Newtonian mechanics. Both subjects have since flourished into extremely active subjects with connections to many parts of mathematics and the physical sciences. Progress has been especially rapid in the last few years in differentiable dynamics and homogeneous dynamics. Differentiable dynamics studies flows on smooth manifolds and has links with geometry while homogeneous dynamics is the study of subgroup actions on homogeneous spaces of Lie groups and has connections to number theory. It is the aim of this two week workshop to ga ther top experts in these two subjects to deliver expositions on the state of the art in these subjects. The first week will be devoted to differentiable dynamics and the second week to homogeneous dynamics.

**DEADLINE: 15/05/2019**

Europe/Rome The main focus is on recent developments in gauge theories, both in theoretical physics and in mathematics. This area is very fruitful for active interplays between Mathematics and Physics. In theoretical physics exact results in supersymmetric quantum field theories and superstrings on curved backgrounds prompted the interest in explicit calculations of (equivariant) Donaldson invariants also in higher rank and the possible definition of new invariants for four manifolds using non-Lagrangian theories. On the mathematical side, new results have been obtained for higher rank Donaldson invariants and Vafa-Witten invariants. A key role is played by the interplay of with representation theory and quantum integrable systems. These developments are also expected to have impact on enumerative geometry, knot theory and representation theory of infinite dimensional algebras. A key technical tool in these developments is equivariant localization which allows the extraction of exact results. Topics : higher rank Donaldson invariants Vafa-Witten invariants Donaldson-Thomas invariants study of the BPS spectra of (non Lagrangean) N=2 Gauge Theories and new four-dimensional invariants relation to matrix models and topological strings quantum Hitchin systems and character varieties gauge theories on complex toric surfaces and their instanton moduli spaces surface operators in gauge theory and moduli spaces of principal bundles with parabolic structure quantum cohomology of the instanton moduli space K-theory of quiver varietes quantum integrability, quantum Yang-Baxter equations relations to knot theory and Khovanov Homology higher dimensional supersymmetric gauge theories and M-theory Lecturers: L.
