Let
be an
-dimensional
umbilic-free spacelike hypersurface in the
-dimensional Lorentzian
space
. One can define
the conformal metric
on
which is invariant under the conformal transformation group of
. We classify the
-dimensional
spacelike hypersurfaces with constant sectional curvature with respect to the conformal
metric
when
.
Such spacelike hypersurfaces are obtained by the standard construction of
cylinders, cones or hypersurfaces of revolution over certain spirals in the
-dimensional
Lorentzian space forms
,
respectively.
