2-Ruled hypersurfaces in Minkowski 4-space and their constructions via octonions
Ameth Ndiaye, Zehra Özdemir
In this paper, we define three types of 2-Ruled hypersurfaces in the Minkowski 4-space . We obtain Gaussian and mean curvatures of the 2-ruled hypersurfaces of type…

On Completely Solvable Lie Foliation
Ameth Ndiaye
In this paper we try to generalize the Haefliger theorem on completly solvable Lie foliations. We prove that: every completely solvable Lie foliation on a compact manifold is the i…

On fibering compact manifold over the circle
Ameth Ndiaye
In this paper, we show that any compact manifold that carries a SL(n;R)-foliation is fibered on the circle S^1.
