“…The theory of graph limits has been extensively developed for dense graph sequences [7,21,22,8,10,9], but the sparse case is not as well understood. In this paper, we study a model introduced and studied in a sequence of papers [11,26,3,17,25,18,4] based on the notion of graphexes. In contrast to the graphons of the dense theory, which are symmetric two-variable functions defined over a probability space, graphexes are defined over σ-finite measure spaces, and, in addition to a graphon part W , contain two other components: a function S taking values in R + , and a parameter I ∈ R + .…”
