We study slant submanifolds of quaternion Kaehler manifold and in particular of a quaternion projective space. We obtain a sharp estimate of the Ricci tensor of a slant submanifold M in a quaternion projective space in terms of the main extrinsic invariant, namely the square mean curvature.
Nous définissons et étudions des sous-variétés obliques dʼune variété Kahlerienne quaternionienne et plus particuliérement dʼun espace projectif quaternionien. Nous obtenons une estimation fine du tenseur de Ricci dʼune sous-variété oblique M dans un espace projectif quaternionien, en termes de lʼinvariant extrinsèque principal, à savoir la courbure moyenne quadratique.
