 The bundle formula_99 described above is given by

where formula_101 is the bundle of holomorphic vectors.The real form of this is given by formula_102, the bundle given at a point formula_103 concretely in terms of the complex structure, formula_104, on formula_98 by

and the almost complex structure on formula_67 is just the restriction of formula_104.The Sphere is an example of a CR manifold with constant positive Webster curvature and having zero Webster torsion.
