Le rang de certaines variétés closes
Annales de l'Institut Fourier, Volume 20 (1970) no. 1, pp. 1-19.

Let M be a closed and connected n-manifold with a locally free action ϕ of R n-1 on M, we prove : if π 1 (M) has no element of finite order the inclusion of a leaf of ϕ into M induces a monomorphism between the fundamentals groups.

As an application we prove that the rank of S 3 ×T n-3 is n-2.

Soit M une n-variété close et connexe munie d’une action localement libre ϕ de R n-1 sur M, on démontre : si π 1 (M) ne contient pas d’éléments d’ordre fini, l’inclusion de toute feuille de ϕ dans M induit un monomorphisme des groupes fondamentaux.

Comme application on prouve que le rang de S 3 ×T n-3 est n-2.
