Title: Causal sets: Discrete, non-local quantum gravity

Abstract: The causal set programme is an approach to finding a theory of quantum gravity. It replaces the differentiable manifold of general relativity with a discrete partially ordered set. In this way it is possible to discretise space-time while retaining Lorentzian invariance. The downside is that this discretisation introduces non-local effects into the theory. In this talk I will give an introduction into causal set theory and talk about these non-local effects and first attempts to reconstruct locality.
