Title: Recovering spacetime topology from a causet
Abstract: An important question which discrete approaches to quantum gravity must address is how continuum features of spacetime can be recovered from the discrete substructure. We examine this question in the causal set approach to quantum gravity. By defining a new topology on causal sets, we show that it is possible to recover the homology of the continuum from a causal set which embeds into a globally hyperbolic spacetime at sufficiently high sprinkling density.
