Dowker F, Imambaccus N, Owens A, Sorkin R, Zalel Set al., A manifestly covariant framework for causal set dynamics

We propose a manifestly covariant framework for causal set dynamics. Theframework is based on a structure, dubbed covtree, which is a partial order oncertain sets of finite, unlabeled causal sets. We show that every infinite pathin covtree corresponds to at least one infinite, unlabeled causal set. We showthat transition probabilities for a classical random walk on covtree induce aclassical measure on the $\sigma$-algebra generated by the stem sets.

Dowker F, Sorkin RD, Symmetry-breaking and zero-one laws

We offer further evidence that discreteness of the sort inherent in a causalset cannot, in and of itself, serve to break Poincar{\'e} invariance. Inparticular we prove that a Poisson sprinkling of Minkowski spacetime cannotendow spacetime with a distinguished spatial or temporal orientation, or with adistinguished lattice of spacetime points, or with a distinguished lattice oftimelike directions (corresponding respectively to breakings ofreflection-invariance, translation-invariance, and Lorentz invariance). Alongthe way we provide a proof from first principles of the zero-one law on whichour new arguments are based.
