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.

WebAug 20, 2024 · To say a graph is regular says only that all vertices have equal degrees, and since graph automorphisms preserve adjacency, vertex transitivity implies regularity but is not equivalent to that (vertex transitivity is a stronger condition). 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.
