On the codimension-one foliation theorem of W. Thurston
Résumé
We are dealing with an $n$-manifold equipped with a $\Ga_n$-structure in the sense of Haefliger with a transverse geometric structure. Here we mainly consider $\Ga_n$-structures transversally codimension-one foliated. We prove a regularization theorem which implies the celebrated theorem of W. Thurston.
