We analyze the proximity measure introduced by Pappis and, give a general definition of proximity measure in this paper. Based on the axiom definition of similarity measure, we discuss some properties of similarity measure. The results, to some extent, could simplify the process of comparison of som

This note presents a measure of similarity between connected nodes in terms of centrality based on Euclidean distances, and compares it to 'assortative mixing' [Newman, M.E.J., 2002. Assortative mixing in networks. Physical Review Letters 89, 208701], which is based on Pearson correlation coefficien
A simple proof is given for the fact that the number of nonsingular similarity relations on (1,2,... n), for which the transitive closure consists of k blocks, equals ("\*;'\_i-') -(2"-fh -'), 1, =G k s n/2. In particular, this implies a recent result of Shapiro about Catalan numbers and Fine's Jequ
