These particles exist in the generalized space-time [[??].sub.4], which is determined as an immediate generalization of the Riemannian space-time [V.sub.4] of General Relativity (both at the differential-geometric manifold and sub-manifold levels): [[??].sub.4] = [V.sub.4] [union] Z, where Z is the zero-space.
In this work, we are interested in studying the metric in a Riemannian space-time which can be written in 3+1 split form:
