Professor Octav Cornea appointed next director of the Centre de recherches mathématiques (CRM)

Professor Octav Cornea has been appointed the next CRM director, effective July 1, 2021, for a four-year term. He will follow in the footsteps of Professor Luc Vinet who has held this position since 2013 and who writes:
"I am very happy that Octav Cornea will follow me at the helm of the CRM. By accepting these responsibilities, he demonstrates an altruism that honors him. I have no doubt that the CRM will continue its remarkable history and excel more than ever under his leadership."

Professor in the Department of Mathematics and Statistics of the Université de Montréal since 2003, Octav Cornea, obtained his doctorate at the University of Rochester in 1993 and, in 1994, he became Professor at the University of Lille 1, where he remained until 2002. He was director of the Institut des sciences mathématiques (2006-2009), director of the Séminaire de Mathématiques Supérieures (2010-2019) and deputy director of the Centre de recherches mathématiques (2011-2014). He works in geometry and topology, with contributions to algebraic topology, dynamical systems and, over the last twenty years, mainly to symplectic topology. He was a Simons Fellow (2015-2016), member of the Institute for Advanced Study in Princeton (2015-2016), Research Professor at the Mathematical Science Research Institute at Berkeley (2009) and invited speaker at the Inaugural Mathematical Congress of the Americas in 2013.

"I thank the Québec mathematical community, and, in particular, my predecessor Luc Vinet, for their support. It is a challenging time, of profound restructuring, but it is also a golden era for the mathematical sciences and, together, I hope we will be able to make the most of the ensuing opportunities."

The importance of mathematics and numeracy for Quebec, by Luc Vinet

The 9th edition of Québec économique examines the challenges of digital transformation. Luc Vinet, Director of the CRM, presents an analysis on numeracy and mathematical research essential to training and of economic and general importance for Québec.

This publication by our partner CIRANO is written under the scientific direction of Nathalie de Marcellis-Warin and Benoit Dostie, under the coordination of Geneviève Dufour.

Two closely related topics, numeracy and mathematical research, are discussed. The first is presented as one of the touchstones essential to the training and culture of our fellow citizens and to the competitive development of Québec. Subsequently, an argument emphasizing the economic and general importance of mathematical research is offered. Québec is very well served in both respects through the "En avant math!" initiative and the CRM respectively, and for this reason, these two organizations deserve all the support possible to strategically position Québec.

In memoriam : Pavel Winternitz

Pavel Winternitz died on February 13, 2021 in Montréal. The CRM loses one of its pioneers. Professor Winternitz had a long and fruitful career, first as a researcher at the CRM, then as a professor at the Université de Montréal's Department of Mathematics and Statistics where he made a significant contribution to the development of mathematical physics. With an unusual passion for research, he still very actively pursued his work in the CRM's mathematical physics laboratory. His kindness and friendship will be sorely missed.
To learn more about his important contributions, we invite you to read this press release.

The proof of the Duffin-Schaeffer conjecture applauded by Québec Science

What Richard Duffin and Albert Schaeffer had postulated in 1941, Dimitris Koukoulopoulos (Université de Montréal) and James Maynard (University of Oxford) finally proved in 2019, then published in 2020. The conjecture 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 (University of Montreal). You can read about the major advances selected by Québec Science for 2020 and vote before Monday, February 8, 2021 at 11:59 p.m. (EST).
