Abstract
Markov categories have recently gained prominence as a higher-level language for probability and statistics, and for causal inference in particular. This language facilitates a treatment of continuous variables and general measure-theoretic probability with the same ease as for discrete variables and facilitates clear and general proofs of many qualitative results (such as the d-separation criterion or certain 0/1-laws). In this talk, I will give a gentle introduction to Markov categories, and subsequently illustrate the formalism by presenting the inflation technique in terms of Markov categories. The inflation technique is a hierarchy of tests which are necessary and (in the limit) sufficient conditions to decide the compatibility of a given probability distribution with a given causal structure with latent variables.
