On étudie une structure nouvelle, dite spinnable, sur des variétés différentielles. On dit qu’une variété différentielle est spinnable si elle peut tourner autour d’une sous-variété de codimension 2 qui s’appelle l’axe, comme une toupie.
Le résultat principal de cet article est le suivant : soit une variété différentielle compacte, -connexe de dimension , du feuilletage de codimension 1 sur , on en déduit que admet une feuilletage de codimension 1.
In this paper we study a new structure, called a spinnable structure, on a differentiable manifold. Roughly speaking, a differentiable manifold is spinnable if it can spin around a codimension 2 submanifold, called the axis, as if the top spins.
The main result is the following: let be a compact -connected -dimensional differentiable manifold , then admits a spinnable structure with axis . Making use of the codimension-one foliation on , this yields that admits a codimension-foliation.
