Causal boundary for stably causal spacetimes
General Relativity and Gravitation, 1988Ths is another step to improve the Geroch-Kronheimer-Penrose boundary construction for space-times. A new identification rule is proposed on the set of ideal points of a space-time which seems to be more satisfactory in the stably causal case. But it remains difficult to describe the corresponding equivalence relation explicitly.
