Almost Weyl structures on null geometry in indefinite Kenmotsu manifolds
-
Fortuné Massamba
Abstract
We introduce and investigate a new concept of almost Weyl structures on null hypersufaces in indefinite Kenmotsu manifolds, tangent to the structure vector field. We show that, under some conditions, there are foliations on almost Weyl null hypersufaces which are Einstein-Weyl with scalar curvature of constant sign.
