Minguzzi %J Mathematics %D 2008 %I arXiv %R 10.1007/s00220-009-0794-4 %X It is proven that K-causality coincides with stable causality, and that in a K-causal spacetime the relation K^+ coincides with the Seifert's relation. As a consequence the causal relation "the spacetime is strongly causal and the closure of the causal relation is transitive" stays between stable causality and causal continuity. %U http://arxiv.org/abs/0809.1214v1
