Approximation of the geodesic curvature and applications for spherical geometric subdivision schemes
Aziz Ikemakhen, Mohamed Bellaihou
Many applications of geometry modeling and computer graphics necessite accurate curvature estimations of curves on the plane or on manifolds. In this paper, we define the notion of…
Four-dimensional homogeneous semi-symmetric Lorentzian manifolds
Abderazak Benroumane, Mohamed Boucetta, Aziz Ikemakhen
We give a complete description of semi-symmetric algebraic curvature tensors on a four-dimensional Lorentzian vector space and we use this description to determine all four-dimensi…
Symplectic structures on the tangent bundle of a smooth manifold
Abouqateb Abdelhak, Mohamed Boucetta, Aziz Ikemakhen
We give a method to lift -tensors fields on a manifold to build symplectic forms on . Conversely, we show that any symplectic form $\Om$ on is symplectomorphic,…
Parallal Spinors on Pseudo-Riemannian SpinC Manifolds
Aziz Ikemakhen
We describe, by their holonomy groups, all simply connected irreducible non-locally symmetric pseudo-Riemannian SpinC manifolds which admit parallel spinors. So we generalise the R…
Parallel Spinors on Pseudo-Riemannian Spin C Manifolds
Aziz Ikemakhen
We describe, by their holonomy groups, all complete simply connected irreducible non-locally symmetric pseudo-Riemannian SpinC manifolds which admit parallel spinors. So we general…
