K-causality coincides with stable causality
نویسنده
چکیده
It is proven thatK-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.

On the relationship between stable causality and K-causality
Hawking’s stable causality implies Sorkin and Woolgar’s K-causality. The work investigates the possible equivalence between the two causality requirements, an issue which was first considered by H. Seifert and then raised again by R. Low after the introduction of K-causality. First a new proof is given that a spacetime is stably causal iff the Seifert causal relation is a partial order. It is t...

T he main objective of this paper was the investigation of the impact of the trade openness on economic growth in Pakistan. We have been employed both the Johensen and Autoregressive Distributed Lag (ARDL) Co-integration together with ECM Techniques for the period 1975-2016. The empirical estimated results are the sound evidence that there exists a short...

T his study evaluates the causality relationship between human capital and foreign direct investment inflow in twenty-six OIC (the Organization of Islamic Cooperation) countries over the period 1970–2014. We employed the panel Granger non-causality testing approach of Kònya (2006) that is based on seemingly unrelated regression (SUR) systems, and Wald tests with country specific boot...
