Any rigged null hypersurface is provided with two shape operators: with respect to the rigging and the rigged vector fields respectively.
The present paper deals with the Newton transformations built on both of
them and establishes related curvature properties. The laters are used to
derive necessary and sufficient conditions for higher-order umbilicity and maximality we introduced in passing, and develop general Minkowski-type
formulas for the null hypersurface, supported by some physical models in
perfect-fluid space-times. |
