Spacetime can be represented minimally as an arbitrary set equipped with a family of real functions that, the author argues, retains the essential causal, topological, and metric content.

abstract
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.

Destructuring Physics: A functional derivation of spacetime
