rotational field

The paper gives the position vector field of the rotational spacelike hypersurface in Lorentz-Minkowski space. After computing the principal curvatures and solving the differential equation system, it proves the existence of the rotational spacelike hypersurface about given principal curvature function in Lorentz-Minkowski space.
