On contact screen conformal null submanifolds
Samuel Ssekajja
First, we prove that indefinite Sasakian manifolds do not admit any screen conformal -null submanifolds, tangent to the structure vector field. We, therefore, define a special c…
A Ricci-type flow on globally null manifolds and its gradient estimates
Mohamed H. A. Hamed, Fortuné Massamba, Samuel Ssekajja
Locally, a screen integrable globally null manifold splits through a Riemannian leaf of its screen distribution and a null curve tangent to its radical distr…
New classes of null hypersurfaces in indefinite Sasakian space-forms
Samuel Ssekajja
We introduce two classes of null hypersurfaces of an indefinite Sasakian manifold, , tangent to the characteristic vector field , called; {\it c…
Remarks on screen integrable null hypersurfaces in Lorentzian manifolds
Samuel Ssekajja
In the present paper, we show that the geometry of a screen integrable null hypersurface can be generated from an isometric immersion of a leaf of its screen distribution into the…
