Abstract

G\'abor Elek introduced the notion of a hyperfinite graph family: a collection of graphs is hypefinite if for every ϵ>0\epsilon>0 there is some finite kk such that each graph GG in the collection can be broken into connected components of size at most kk by removing a set of edges of size at most ϵV(G)\epsilon|V(G)|. We presently extend this notion to a certain compactification of finite bounded-degree graphs, and show that if a sequence of finite graphs converges to a hyperfinite limit, then the sequence itself is hyperfinite.
