On donne une obstruction topologique pour qu’un feuilletage soit un sous-feuilletage d’un autre en comparant les images des homomorphismes caractéristiques associés (dans le sens de Lehmann).
A topological obstruction for a foliation be a sub-foliation of another is given by comparing the images of the associated characteristic homomorphisms (in the sense of Lehmann).
