A causet is a locally finite partially ordered set. A faithful embedding of a causet $C$ into a spacetime $(M,g)$ at density $\rho$ is a map … such that $\Phi(C)$ is a high-probabi…

Let $(M,g)$ be a spacetime, where $M$ is a differentiable manifold and $g$ is its Lorentzian metric. At the quantum level, spacetime is expected to be far less regular than at the…

Exhaustion conjecture. The topologies described in Theorem 2 exhaust all possible spacetime topologies belonging to the class $\mathfrak{Z}-\mathfrak{G}$ that admit a countable bas…
