Michał Eckstein, Tomasz Miller
Drawing from the theory of optimal transport we propose a rigorous notion of a causal relation for Borel probability measures on a given spacetime. To prepare the ground, we explor…

Causality in noncommutative two-sheeted space-times
Nicolas Franco, Michał Eckstein
We investigate the causal structure of two-sheeted space-times using the tools of Lorentzian spectral triples. We show that the noncommutative geometry of these spaces allows for c…
