Graphons and Graph Limits 1

links:none on file
slides:none on file

Dense graph sequences have a single concrete limit object: graphon = W:[0,1]^2→[0,1], a symmetric feature-kernel that generates inhomogeneous random graphs by sampling vertex features and connecting independently with probability W(x,y). Multiple practical similarity tests—normalized induced subgraph counts, sampling distributions, multiway cut values and microcanonical free energies—are provably equivalent (technical proofs span ~100 pages). Exchangeable infinite arrays admit the Aldous–Hoover representation (possibly random W); DeFinetti/Polya‑urn intuition explains why conditioning on latent features yields conditional independence.
