Following Ghilardi and Meloni, a relational variable set on a category B is a lax functor B to Rel, where Rel is the category of sets and relations. Change-of-base functors and their adjoints are considered for certain categories of relational variable sets and applied to construct the simplification of a dynamic set (in the sense of Stell).
