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…
Some symmetry properties of four-dimensional Walker manifolds
Abdoul Salam Diallo, Fortuné Massamba
In this paper, we investigate geometric properties of some curvature tensors of a four-dimensional Walker manifold. Some characterization theorems are also obtained.
Quasi Generalized CR-lightlike submanifolds of indefinite nearly Sasakian manifolds
Fortuné Massamba, Samuel Ssekajja
In this paper, we introduce and study a new class of CR-lightlike submanifold of an indefinite nearly Sasakian manifold, called Quasi Generalized Cauchy-Riemann (QGCR) lightlike su…
On three dimensional affine Szabó manifolds
Abdoul Salam Diallo, Silas Longwap, Fortuné Massamba
In this paper, we consider the cyclic parallel Ricci tensor condition, which is a necessary condition for an affine manifold to be Szabó. We show that, in dimension , there are…
Some remarks on quasi generalized CR-null geometry in indefinite nearly cosymplectic manifolds
Fortuné Massamba, Samuel Ssekajja
In [21], the authors initiated the study of quasi generalized CR (QGCR)-null submanifolds. In this paper, attention is drawn to some distributions on ascreen QGCR-null submanifolds…
Sasakian Finsler structures on pulled-back bundle
Fortuné Massamba, Salomon Joseph Mbatakou
Under a pulled-back approach given in [1] and firstly presented in [2], we introduce, in this paper, the concepts of almost contact and normal almost contact Finsler structures on…
