Description
I will discuss aspects of the path sum of causal set theory, in which the continuum is replaced by a sample space of locally finite partially ordered sets. This sample space not only contains continuumlike causals of different dimensions, but an entire zoo of non-continuumlike ones. An open question is whether this path sum can be treated as a UV regularisation of the continuum path integral, as the number of elements increases. I will discuss some results as well as challenges in answering this question.
