Local density of diffeomorphisms with large centralizers
[Densité locale des difféomorphismes ayant un gros centralisateur]
Annales scientifiques de l'École Normale Supérieure, Série 4, Tome 41 (2008) no. 6, pp. 925-954.

Pour toute variété M compacte, de dimension quelconque, nous construisons une partie 𝒪 Diff 1 (M) non vide, ouverte dans l’espace Diff 1 (M) des C 1 -difféomorphismes de M, et un sous-ensemble 𝒟𝒪 dense en 𝒪, constitué de difféomorphismes dont le centralisateur est non dénombrable, donc non trivial.

Given any compact manifold M, we construct a non-empty open subset 𝒪 of the space Diff 1 (M) of C 1 -diffeomorphisms and a dense subset 𝒟𝒪 such that the centralizer of every diffeomorphism in 𝒟 is uncountable, hence non-trivial.
