CR-Submanifolds of Almost Hermitian Manifolds,Let N be a n-dimensional almost Hermitian manifold with almost complex structure J and with Hermitian metric g. LetH be a real m-dimensional Riemannian manifold isometrically immersed in N.

CR-Structures and Relativity,The main purpose of this chapter is to show that CR-structures on real hypersurfaces of a complex manifold have an interesting application to relativity. It is the merit of Roger Penrose to discover a correspondence between points of a Minkowski space and projective lines of a certain real hypersurface in a complex projective space (see (2.4)).

CR-Structures and Pseudo-Conformal, Mappings,act manifolds (see Blair [3],p. 62) are examples of ~R-manifolds. Non-trivial CRmanifolds appeared as boundaries of domains in complex spaces, which in fact are real hypersurfaces (i.e.,particular CR-submanifolds).
