Description
I will give an overview of quantum dynamics in causal set theory. Because of the fundamental (causal) non-locality of causal sets, the dynamics is best described in the language of histories or the path integral formulation. The approach, to date, has been broadly two pronged: the first uses a continuum-inspired partition function and the discrete Einstein Hilbert action while the second uses first principles to construct the decoherence functional within a "growth" paradigm. I will describe recent progress in both and the open questions and challenges that remain.
