Olivier Lafitte, new CNRS Director of the UMI-CRM in Montréal


Olivier Lafitte is professor at the Galilée Institute of Paris 13 University in Villetaneuse since 2001. His areas of interest are varied, around partial differential equations and ordinary differential equations. He has been collaborating with Montréal colleagues for a long time. At the direction of the UMI-CRM (created in 2011 and co-led by the director of the CRM, Luc Vinet), Olivier Lafitte's mission is to develop collaborations and exchanges between the French and Québec mathematical communities. Research teams, who have or want to set up projects, are invited to contact him at lafitte@crm.umontreal.ca or 514-343-6111, extension 4726.


Launched in 1991 by the Centre de recherches mathématiques (CRM), the André-Aisenstadt Prize offers talented young Canadian mathematicians a scholarship and medal for outstanding research achievements.


The recipient is invited to deliver a lecture at the CRM and to write a brief article on his or her work for publication in the Bulletin of the CRM.

An international jury

The CRM's International Scientific Advisory Committee advises the CRM on all its major scientific orientations and chooses the recipient each year. The last recipient, Yaniv Plan, will give his lecture on November 15, 2019 at 4 pm in room 6214 at Pavillon André-Aisenstadt.

Deadline: March 1st, 2020

Bruno Rémillard, SSC Gold Medalist 2019

remillard This year’s recipient of the Gold Medal of the Statistical Society of Canada is Bruno N. Rémillard. This prestigious award is bestowed upon a person who has made outstanding contributions to statistics, or to probability, either to mathematical developments or in applied work. It is intended to honour current leaders in their field. Bruno Rémillard is professor at HEC Montréal and member of the CRM Statistics laboratory. Professor Rémillard was also nominated IMS Fellow for 2019. | Read more

Dimitris Koukoulopoulos makes waves by proving the celebrated Duffin-Shaeffer conjecture

KoukoulopoulosandMaynard Professor Dimitris Koukoulopoulos, a member of the CICMA lab of the Centre de recherches mathématiques (CRM) and Professor in the Mathematics Department of the Université de Montréal, has caused a sensation by proving the long-standing Duffin-Schaeffer conjecture in collaboration with Professor James Maynard from Oxford University. The Duffin-Schaeffer conjecture is a vast generalization of Liouville's famous theorem on the approximation of real numbers by rational numbers. Formulated in 1941, it had long resisted the efforts of the best researchers and its proof represents a milestone in metric diophantine approximation. Koukoulopoulos and Maynard were postdoctoral researchers at the Centre de recherches mathématiques, from 2010 to 2012, and from 2013 to 2014 respectively, under the supervision of Professor Andrew Granville of the Université de Montréal. Their proof involves the "pretentious" perspective in analytic number theory pioneered by Granville in collaboration with Professor Kannan Soundararajan of Stanford University.

Thomas J. Bothner: winner of the 2019 Gábor Szegö Prize

The Centre de recherches mathématiques would like to congratulate Thomas J. Bothner on the 2019 Gábor Szegö Award just given to him at the 15th OPSFA Symposium (Orthogonal Polynomials, Special Functions and Applications) which took place in Hagenberg, Austria. Thomas J. Bothner is Professor at the Department of Mathematics at King's College London. He was a CRM-ISM Postdoctoral Fellow from 2013 to 2015. The SIAM Activity Group on Orthogonal Polynomials and Special Functions (SIAG/OPSF) awards the Gábor Szegö Prize every two years since 2011 to an early career researcher for outstanding contributions. Thomas J. Bothner was very happy to receive this prize.

Jean-Philippe Lessard nominated deputy director of scientific activities at the CRM

Lessard On July 1, Jean-Philippe Lessard, professor at McGill University, was nominated deputy director of scientific programs for a two-year term. His research interests include applied mathematics, numerical analysis and partial differential equations. He replaces Louigi Addario-Berry, who has been a brilliant member of the CRM management team since 2015. We extend our sincere thanks.

Creation of the Endowment Fund Robert Langlands

The Centre de recherches mathématiques (CRM) of the Université de Montréal is proud to announce the creation of the Robert Langlands Endowment Fund. This fund will finance CRM activities promoting the use of the French language. These activities include training and research in mathematics in Quebec and Canada. | En savoir plus

Renewal of the subsidy granted to the UMI-CRM

The Fonds de recherche Nature et technologies (FRQNT) has confirmed the renewal of a grant of $ 300,000 to the Unité Mixte Internationale (UMI) Centre de recherches mathématiques (CRM). | Read more

The CRM welcomes the Montreal Declaration for a Responsible Development of Artificial Intelligence

The Centre de recherches mathématiques welcomes the Montreal Declaration for a Responsible Development of Artificial Intelligence unveiled on December 4, 2018. The CRM, partner of MILA and IVADO, endorses this statement. One of its objectives is "to promote the digital transition so that everyone can benefit from this technological revolution". To this end, the CRM, in collaboration with CIRANO, has recently been mandated by the Quebec government to develop a national initiative to increase numeracy. | Read more

CRM Laboratories

Mathematical Analysis
Both classical and central to modern mathematics, mathematical analysis lies at the core of our understanding of any continuous system. The mathematical analysis laboratory has undertaken in-depth studies of dynamical systems, partial differential equations and spectra of operators.

The objective of CAMBAM (Center for Applied Mathematics in Bioscience and Medicine) is the application of mathematics to address biological challenges across all levels of biological organisation ranging from the molecular/genetic through single cell and whole organ physiology to population and ecosystem dynamics.

CICMA is an inter-university research center officially established in 1989. Its research activities are concentrated on number theory, arithmetic geometry, computational algebra and sporadic finite groups.

CIRGET is a joint force of researchers at the cutting-edge of international research in differential geometry, topology, geometric group theory and mathematical physics.

GIREF gathers researchers and research groups from several academic institutions in order to facilitate research, development, training of specialists and interaction with the industrial circles in the field of modeling an numeric simulation.

Founded in 1982, LaCIM is one of the principal research center in combinatorics, algebraic combinatorics and theoretical computer science on the international scene.

Applied Mathematics
As a result of state-of-the-art computational resources, it has become possible to simulate problems and figure solutions that we only dreamed of a decade ago. This has been a driving force in the creation of this laboratory.

Mathematical Physics
Mathematical physics represents one of the traditional strengths of the CRM since the beginning of the 1970's. Research focus on several of the most active scientific areas in mathematical physics.

Montreal Institute for Learning Algorithms (MILA)
Artificial intelligence and machine learning are dynamic and ever-expanding disciplines. The incorporation of MILA into the CRM will give the CRM a more important role within the so-called “digital strategy” of the Québec government.

The work of PhysNum is focused on cerebral imaging and its method. Started within a collaboration with INSERM (Hôpital Pitié-Salpêtrière) and the Institut universitaire de gériatrie de Montréal, this trend took shape during the study of reconstruction signals in magnetoencephalographic problems.

Probability lab members pursue research in a broad range of areas, spanning theoretical and applied, continuous and discrete probability. A particular focus is on the development and analysis of probabilistic models for real-world phenomena from physics, biology, statistics and computer science.

The Actuarial and Financial Mathematics Laboratory is an inter-university group of researchers focused on the mathematics of actuarial science and finance. Its research activities are concentrated on the applications of probabilistic and statistical techniques to analyze random events with financial impact.

Statistics is central to many endeavours in society. Whether it be through surveys from sampling, clinical trials to study various biomedical treatments or experimental designs in agriculture or industry, statistical methodology can be found everywhere in science. The statistics laboratory rallies a great number of statisticians from Eastern Canada.
