CIRM hosts several scientific events each week, which unfortunately cannot be held at present. 
Meetings and exchanges are the very essence of CIRM. Since the announcement of the containment, our team has been working to set up a complete audiovisual environment so that organizers can still maintain their event in a virtual form. 
We use the Big Blue Button videoconferencing system – linked to our servers, our YouTube channel and our Audiovisual Mathematics Library. In this way, conferences can be recorded and uploaded online at the same time. Our teams take care of all the technical aspects so that the organizers and speakers, just like during their stay at CIRM, can concentrate solely on their scientific presentations. 
So that science and exchanges may continue!

Mathematical Methods of Modern Statistics 2
Méthodes Mathématiques en Statistiques Modernes 2


​15 – 19 June 2020

After the success of the first CIRM-Luminy meeting on Mathematical Methods of Modern Statistics (July 2017) we would like to continue the tradition. The title of the conference makes allusion to the famous book of Harald Cramèr Mathematical Methods of Statistics (1946) which is a landmark both for mathematics and statistics. The main objectives of the conference are to respond on the world highest statistical and mathematical level to:
(a) a strong need of reflection on the interactions between different branches of modern statistics and modern mathematics and of summarizing them
(b) the actual scientific strategy of development of Data Sciences in France and abroad.

We propose a wide spectrum of topics and general paradigms of modern statistics with deep mathematical implications. The major unifying topic is analysis of large dimensional data. The statistical inference based on such data is possible under certain assumptions on the structure of the underlying model, using different notions of model sparsity. The conference talks will give an overview of current knowledge on the modern statistical methods addressing this issue: including modern graphical models, different methods of multiple testing and model selection, regularization techniques and missing data treatments. These topics will be viewed both from the frequentist and Bayesian perspective, including modern nonparametric Bayes methods.

Virtual Geometric Group Theory conference

Geometric group theory is the study of infinite discrete groups using geometric techniques inspired broadly by classical Riemannian geometry, while also borrowing ideas from other mathematical domains such as formal language theory and algebraic topology. The field has developed rapidly and is currently very active, with many innovative projects reaching in new directions. This conference will highlight the interaction between two main themes in the field : Artin groups on the one hand, and CAT(0) geometry on the other hand. Although these two themes will be the leitmotivs of the conference, related topics such as Coxeter groups, 3-dimensional manifolds, automorphisms of free groups and mapping class groups are also included in the topics in order to enrich exchanges between participants and inspire ideas for developing new research projects.

Geometry and Dynamics of Foliations ​​

May 18 to 22 


Frédéric Campana (Université de Lorraine)
Frank Loray (CNRS-Université de Rennes I)
Paulo Sad (IMPA)

Stéphane Druel (CNRS-Université Lyon 1)
Jorge Vitório Pereira (IMPA & Aix-Marseille Université)

Foliation Theory is a lively subject lying at a crossroad of many mathematical disciplines. The School “Geometry and Dynamics of Foliations” aims at presenting to young mathematicians some of the  different  techniques used by practitioners of the field. The topics of the mini-courses give a panorama of recent developments in Foliation Theory, ranging from algebraic-geometric to dynamical contributions. 

​This event  is part of  a series of three activities focusing on Foliation Theory and Complex Geometry at CIRM-Luminy in 2020.

Varieties with Trivial Canonical Class
April 13 to 17


Frank Loray (CNRS – Université de Rennes I)
Jorge Vitorio Pereira (IMPA Brazil / Aix-Marseille Université)
Erwan Rousseau (Aix-Marseille Université)
The workshop aims at reviewing the recent decomposition theorem for singular varieties with trivial canonical class. This result is the culmination of efforts of a number of researchers and this workshop brings together most researchers which contributed to the proof of this result. We will also have some talks on the geometry of hyperkähler varieties.
