Many values of the Riemann zeta function at odd integers are irrational
[Beaucoup de valeurs aux entiers impairs de la fonction zêta de Riemann sont irrationnelles]
Comptes Rendus. Mathématique, Volume 356 (2018) no. 7, pp. 707-711.

Dans cette note, on annonce le résultat suivant : au moins 2(1ε)logsloglogs valeurs de la fonction zêta de Riemann aux entiers impairs compris entre 3 and s sont irrationnelles, où ε est un réel strictement positif et s un entier impair suffisamment grand en fonction de ε. Ceci améliore la borne 1ε1+log2logs qui découle du théorème de Ball–Rivoal. On donne les idées principales de la preuve, qui est fondée sur un procédé d'élimination entre des formes linéaires en les valeurs de zêta aux entiers impairs dont les coefficients sont reliés.

In this note, we announce the following result: at least 2(1ε)logsloglogs values of the Riemann zeta function at odd integers between 3 and s are irrational, where ε is any positive real number and s is large enough in terms of ε. This improves on the lower bound 1ε1+log2logs that follows from the Ball–Rivoal theorem. We give the main ideas of the proof, which is based on an elimination process between several linear forms in odd zeta values with related coefficients.
