There is a somewhat clear way to define a distance between two graphs with the same number of vertices. After a slight generalization, we get a distance function that even works for graphs on differing numbers of vertices. We can also consider a sequence G_n of graphs, talk about convergence of a sequence of graphs (generally with the number of vertices going to infinity), and discuss what we mean by a limit. In this talk, I will motivate and define these limit objects, graphons, and talk about in what sense we can say the sequence converges. If time permits, I will also discuss the property of Finite Forcibility, and state a few results in this area.
