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. WebAn arc-transitive graph, sometimes also called a flag-transitive graph, is a graph whose graph automorphism group acts transitively on its graph arcs (Godsil and Royle 2001, p. 59). More generally, a graph G is called s-arc-transitive (or simply "s-transitive") with s>=1 if it has an s-route and if there is always a graph automorphism of G sending each s-route …

WebActually the defining properties of a 2-BMG are unusual apart from bi-transitivity, and a natural question is whether 2-BMGs also have properties which well fit in structural graph theory. In this paper we show some of such properties. A major result is that if a 2-BMG has no equivalent vertices then each of its orientation is acyclic. WebThe local transitivity of an undirected graph.

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 ). WebAnswer (1 of 3): Transitivity is a property of relations throughout math, but in graph theory (and in the theory of group actions) it also means something slightly different: …

WebTo preserve transitivity, one must take the transitive closure. This occurs, for example, when taking the union of two equivalence relations or two preorders. To obtain a new equivalence relation or preorder one must take the transitive closure (reflexivity and symmetry—in the case of equivalence relations—are automatic). In graph theory

Webgraph theory. While earlier works [9, 10] mainly care for asymptotic computational complexity, in recent works, real-life execution time has been a major consideration, motivation for which comes from the enormous size of real-life networks having vertices in the ranges of millions to billions.
