CNRS Mathematics celebrates its 15th anniversary!

Institutional

Almost fifteen years to the day after the ministerial decree establishing its creation, the Insmi (CNRS Mathematics) celebrated its 15th anniversary on Thursday, June 26, 2025. This anniversary was an opportunity to discuss its national missions and its past, present, and future challenges. Here is a chronological look back at a timeless moment.

The event opened with speeches by institutional representatives, including

  • Christophe Besse, Director of Insmi,
  • Gilles Halbout, Advisor on Education, Higher Education and Research to the President of the French Republic,
  • François Germinet, Special Advisor to the Minister for Higher Education and Research,
  • Valérie Pécresse, President of the Île-de-France Regional Council (recorded speech), who signed the decree as Minister for Higher Education and Research,
  • and Antoine Petit, CEO of the CNRS.

I remain convinced that without Insmi and CNRS, mathematical research in France would not be what it is today.

The afternoon continued with a round table discussion, “Different perspectives on a national institute for mathematics,” moderated by Matthias Cléry of the Committee for the History of the CNRS, with the participation of:

French mathematics is all the stronger because it is strong everywhere.

The rest of the program was devoted to a review of the history of the discipline since the creation of the Insmi, through the presentation “Mathematics at the CNRS, from prehistory to the Insmi,” by Matthias Cléry and Denis Guthleben of the Committee for the History of the CNRS (Comité pour l'histoire du CNRS).

After a short break, the audience enjoyed two scientific presentations: “Optimal transport and data science,” presented by Julie Delon, university professor at MAP5 and winner of the 2024 CNRS Silver Medal, and “Algebraic geometry starting from conic sections,” presented by Alessandra Sarti, deputy scientific director of Insmi in charge of research units and researchers.

The creation of Insmi was first mentioned in 2007. It was important to defend a stable scientific policy (I had four general directors and three scientific directors...) that was accepted by the mathematical community and by partner universities. The repeated affirmation of this policy heralded its permanence and perhaps the creation of Insmi.

Finally, there will be a highlight of video testimonials punctuated by speeches from Guy Métivier, director of Insmi from 2010 to 2013, Christoph Sorger, director of Insmi from 2013 to 2017, and Pascal Auscher, director of Insmi from 2017 to 2021.

The afternoon ended on a festive note with a 15-question quiz, before everyone blew out the 15 birthday candles together.

The Insmi management is merely a conduit for community projects, and that is its essence. This should not be forgotten.
