Towards a Characterization of Universal Categories

Category Theory 2016-08-04 v1 Combinatorics

Abstract

In this note we characterize, within the framework of the theory of finite set, those categories of graphs that are {\em algebraic universal} in the sense that every concrete category embeds in them. The proof of the characterization is based on the sparse--dense dichotomy and its model theoretic equivalent.
