A conformal connection on null hypersurfaces of indefinite Kenmotsu manifolds (Q1684265)

The article defines the indefinite Kenmotsu manifolds as odd-dimensional indefinite Riemannian manifolds equipped with contact structures, such that their Levi-Civita connections satisfy additional equations. It studies some null hypersurfaces in indefinite Kenmotsu manifolds. The following is taken from its abstract: ``Proper totally contact umbilical integral manifolds of screen integrable null hypersurfaces in indefinite Kenmotsu manifolds admit \(\eta\)-Weyl structures. Its geometry is closely related to the one of a normal subbundle over the indefinite Kenmotsu manifold.''
