We study some properties of a lightlike hypersurface M , of a
Lorentzian manifold, whose shape operator is conformal to the shape operator
of its screen distribution. We prove that some specified aspects of the null
geometry of M reduce to the Riemannian geometry of a leaf of its screen distri-
bution. As a physical relevance, we show that there exists such a class of screen
globally conformal lightlike hypersurfaces of 4-dimensional stationary non-flat
spacetimes which admit a Killing horizon. |
