g-Natural metrics of constant sectional curvature
S. Degla, J. -P. Ezin, L. Todjihounde
We prove that the tangent bundle endowed with a g-natural metrics has constant sectional curvature if and only if it is flat, and then we give a characterization of flat g-natural…

Classification of differentials and Cartan calculus on bicrossproducts
F. Ngakeu, S. Majid, J-P. Ezin
We provide the Cartan calculus for bicovariant differential forms on bicrossproduct quantum groups $k(M)\lrbicross kG$ associated to finite group factorizations and a field…

Reduction of the co-dimension of light-like isotropic sub-manifolds
Cyriaque Atindogbe, Jean-Pierre Ezin, Joël Tossa
We give a sufficient condition for a lightlike isotropic submanifold , of dimension , which is not totally geodesic in a semi-Riemannian manifold of constant curvature an…
