Dans ce livre, nous nous intéressons à la discrétisation et à l'analyse d'erreur a-posteriori de type résiduel des équations du problème couplé Stokes-Darcy. Ces équations modélisent l'écoulement d'un fluide visqueux vers un milieu poreux à travers [...]

In this paper, we generalize the Cartan's fundamental formula on lightlike hypersurfaces, then we use it to show that a screen conformal lightlike hypersurface of a Minkowski space is locally a triple product manifold. [...]

In a recent past, the growing importance of lightlike submanifolds in global Lorentzian geometry and their extensive use in general relativity, motivated their study in a semi-Riemannian manifold. This is the lightlike geometry of (sub-)manifolds [...]
We give a sufficient condition for a lightlike isotropic submanifold M, of dimension n, which is not totally geodesic in a semi-Riemannian manifold of constant curvature c and of dimension n + p(n < p), to admit a reduction of codimension. We show [...]
