Graph theory transitivity

WebThe transitivity coefficient T of a network, also known as clustering coefficient, is the ratio of the number of loops of length three and the number of paths of length two. Hence, it is the frequency of loops of length three in the network. T = 1 implies perfect transitivity, i.e., a network whose components are all cliques. WebTheorem 1. A resolvable network is satisfiable if and only if there is an assignment of 0’s and 1’s to the nodes of the network such that each reach of the network has the following property: there is a node. a ∈ A. such that 0 is assigned to a; or. there is a node. b ∈ B. such that 1 is assigned to b. Proof.

(gEff), transitivity (TR), and modularity (MOD) (Newman, 2006, Rubinov and Sporns, 2010). The graph measures are briefly defined in the following. First, some basic … In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create tightly knit groups characterised by a relatively high density of ties; this likelihood tends to be greater than the average probability of a tie randomly established between two nodes (Holland and Leinhardt, 1971; Watts and Strogatz, 1998 ).

In the mathematical field of graph theory, an edge-transitive graph is a graph G such that, given any two edges e1 and e2 of G, there is an automorphism of G that maps e1 to e2. In other words, a graph is edge-transitive if its automorphism group acts transitively on its edges.
