Short summary

This paper introduces and formalizes two new notions of graph convergence: 'left-convergence' and 'right-convergence', based on homomorphism densities into sequences of dense graphs.

Abstract

We consider sequences of graphs (Gn) and define various notions of convergence related to these sequences including "left-convergence," defined in terms of the densities of homomorphisms from small graphs into Gn, and "right-convergence," defined in terms of the densities of homomorphisms from Gn into small graphs.
