I gave a plenary talk at
SAMPTA 2017 (Sampling Theory and Applications) which took place in Tallin July 3-7 2017.
J'ai été très heureux de participer aux cérémonies et festivités autour de la remise du prix Abel à Yves Meyer à Oslo du 22 au 24 mai 2017, cf. le petit reportage que j'ai effectué pour l'INSMI (et les photos que j'ai prises):
22 mai , 23 mai ,
ainsi que les textes sur les travaux d'Yves Meyer que j'ai écrits sur les site de The Conversation ou pour
la Gazette des Mathématiciens .
June 25-26th 2016: To celebrate its tenth anniversary, the
Quai Branly Museum
organized meetings with CNRS researchers. On this occasion, I presented our joint work with Patrice Abry and Herwig Wendt concerning the classification of Van Gogh paintings and the issues its raises for stylometry.
February 2016: INSMI (CNRS Institute for Mathematics) announced that Wilson Bases
(joint construction with Ingrid Daubechies and Jean-Lin Journé) are a key component of the detection algorithm that located the signature of coalescent binary black holes in gravitational waves. This paper (Gazette des Mathématiciens, April 2016, in french) explains why Wilson bases are used in the detection of gravitational waves.
September-October 2015: Our joint work with Patrice Abry and Herwig Wendt on the classification of Van Gogh paintings based on multifractal attributes was selected by CNRS and RATP as part of the fresco
Le couloir du temps in the corridor of the Paris Metro station Montparnasse.
ANNIVERSARY: In 1916, G.H. Hardy determined the exact pointwise regularity of the
at every point; this article initiated the
study of pointwise regularity of everywhere irregular functions. It also includes the first mathematical results concerning Riemann's non-differentiable function: The first example of a function that would be proved to be multifractal.
IN MEMORIAM: Jean-Lin Journé died in April 2016. He is mostly famous for being the author, with Guy David, of the T(1) theorem, also called the David-Journé theorem, which revolutionized the theory of singular integral operators. I will remember him as a great collaborator, an unorthodox art salesman and an amazingly brilliant intelligence.
