May 21 at 15:31 comment added Bastam Tajik Ok let me ask a better question. Lorentzian distance is not an analytic metric. The question is what sort of Mathematical object is it precisely? @StefanWaldmann
Nov 2, 2023 at 9:19 comment added Stefan Waldmann @Bastam Tajik No, in general not. Already in the example I gave, it is not even Hausdorff.

Aug 16, 2023 at 7:37 comment added Bastam Tajik @StefanWaldmann Very nice answer. Is such topology in general(not only for the strongly causal spacetimes) metric?
Apr 11, 2017 at 14:28 comment added Stefan Waldmann @Willie Wong: yep, of course. This is the evidence from a more conceptual point of view.

Apr 11, 2017 at 14:13 comment added Willie Wong A few remarks: (a) by "this topology" it is meant the Alexandrov/Interval topology defined using the base $I^+(x)\cap I^-(y)$. (b) This topology can be defined on any causal space and does not require strictly a smooth Lorentzian structure (nor, for that matter, a manifold structure on the base). (c) The previous fact should be taken as evidence toward why this topology does not have to coincide with the manifold topology.
