We generalize the classical Minkowski formulae in Euclidean space to spacelike codimension-2 submanifold in spacetimes that admits a “hidden symmetry”. One application is a characterization of when a submanifold lies in a null hypersurface emanated from a round sphere. This is a joint work with Prof. Mu-Tao Wang.
