These operations are sufficient to allow the construction of arbitrary nonseparable networks, starting with a simple circuit. The tree graph of a network is defined as a linear graph in which each vertex corresponds to a tree of the network, and …
WebJan 14, 2024 · Directed Graphs 4.2 Directed Graphs Digraphs. A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. WebFeb 1, 2011 · The sandpile group is an abelian group associated to a directed graph, whose order is the number of oriented spanning trees rooted at a fixed vertex. In the case when G is regular of degree k, we show that the sandpile group of G is isomorphic to the quotient of the sandpile group of L G by its k -torsion subgroup.

WebThis paper describes a new method of finding all the Hamiltonian circuits in an undirected graph, if such circuits exist. The method uses for the first time the mesh description of a graph and it is here applied in cubic graphs.
