${\mathcal{A}}^{\nabla}$-tensors on ligktlike hypersurfaces
Résumé
This paper introduces $\anabla$-tensors on lightlike hypersurfaces $M^{n+1}$ of signature $(0,n)$, $(n\geq 1)$ and investigates on their properties in connection with the null geometry of $M$. In particular, we show that there is an interplay between existence of $\anabla$-tensors of certain type and lightlike warped product structures.
