摘要

We prove that the accumulation points of a sequence of graphs G1, G2 G3,... with respect to the cut-distance are exactly the weak* limit points of subsequences of the adjacency matrices (when all possible orders of the vertices are considered) that minimize the entropy over all weak* limit points of the corresponding subsequence. In fact, the entropy can be replaced by any map W bar right arrow integral integral f(W(x,y)), where f is a continuous and strictly concave function. As a corollary, we obtain a new proof of compactness of the cut-distance topology. (C) 2019 Elsevier Inc. All rights reserved.
