$A^\nabla$-tensors on lightlike hypersurfaces

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/127924This 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.soumisDifferential Geometry53C50, 53C21$A^\nabla$-tensors on lightlike hypersurfacestext
