We study a new graph invariant, the sequence of the number of k‐edge subtrees of a graph. We compute the mean subtree size for several classes of graphs, concentrating on complete graphs, complete bipartite graphs, and theta graphs, in particular. We prove that the ratio of spanning trees to all subtrees in approaches , and give a related formula for . We also connect...
Growing interest in modeling large, complexnetworks has spurred significant research into generative graphmodels. Kronecker-style models (e.g. SKG and R-MAT) are oftenused due to their scalability and ability to mimic key propertiesof real-world networks. Although a few papers theoreticallyestablish these models' behavior for specific parameters, manyclaims used to justify their use are supported...
