## September 17 – October 14, 2018 » Algebra and combinatorics at LaCIM, a conference for the 50th anniversary of the CRM

## March 1 – 31, 2019 » New Developments in Free Probability and Applications

**Organizers: Benoît Collins (Kyoto), James Mingo (Queen’s), Roland Speicher (Saarland), Dan-Virgil Voiculescu (Berkeley)**

## April 1 – 30, 2019 » Topological and Rigorous Computational Methods for High Dimensional Dynamics

**Organizers: Jean-Philippe Lessard (McGill), Konstantin Mischaikow (Rutgers), Jan Bouwe van den Berg (VU Amsterdam)**

The focus of this program is on identifying explicit dynamical structures in nonlinear systems that are high dimensional, poorly resolved, or both. In these problems, computational mathematics is often the only feasible way forward.

The first featured workshop explores the computational challenges of rigorously identifying and extracting fundamental dynamical features such as equilibria, periodic orbits, connecting orbits and invariant manifolds in infinite-dimensional dynamical systems. The second featured workshop investigates the development of computational algebraic topological tools for studying multiparameter, nonlinear systems where the nonlinearities are poorly defined.

The main aim is to identify, characterize, and predict nonlinear dynamics from high-dimensional time series data sets. Each workshop is preceded by a hands-on tutorial aimed at graduate students, postdocs and early- to mid-career mathematicians.

## April 29 – May 17, 2019 » Faces of Integrability

**Organizers: Jacques Hurtubise (McGill), Nicolai Reshetikhin (Berkeley), Lauren K. Williams (Berkeley)**

The theory of integrable systems, with its origins in symmetries, has intricate ties to a wide variety of areas of mathematics. Sometimes the ties are straightforward, but in many cases, the links are more complicated, and indeed somewhat difficult to make explicit. Some of these interfaces, between integrability, geometry, representation theory, and probability theory will be dominating subjects during the conference and satellite activities. Themes to be covered include the role of cluster algebras and cluster varieties in the description of moduli spaces, the links between integrable systems and representation theory appearing in such areas as quantum groups and quantization of moduli spaces, and the fascinating interfaces of probability theory, combinatorics and integrable systems appearing in several processes linked to statistical mechanical models.

During the first week of activities, April 29 – May 3), introductory lectures for graduate students will take place. It will consist of four four-hour series of lectures:

Gaétan Borot (MPIM)

“Geometric and topological recursion”

Mikhael Gekhtman (Notre Dame)

“Cluster Integrable Systems”

Nicolai Reshetikhin (Berkeley)

“An overview of the construction of integrable systems based on factorizable Poisson Lie groups”

Hugh Thomas (UQAM)

“Introduction to cluster algebras”

A conference will take place during the second week, May 6-10.
