Conformal curvature for the normal bundle of a conformal foliation
Annales de l'Institut Fourier, Tome 32 (1982) no. 3, pp. 261-274.

On prouve que le fibré normal ℋ d’une distribution 𝒱 dans une variété riemannienne admet une courbure conforme C si et seulement si 𝒱 est un feuilletage conforme. Alors, ℋ est conformément plat si et seulement si C est nulle. De plus, on peut exprimer les classes de Pontrjagin de ℋ en fonction de C.

It is proved that the normal bundle ℋ of a distribution 𝒱 on a riemannian manifold admits a conformal curvature C if and only if 𝒱 is a conformal foliation. Then ℋ is conformally flat if and only if C vanishes. Also, the Pontrjagin classes of ℋ can be expressed in terms of C.
