Webof circuits, especially when several matroids are being considered. Theorem 1.3. Let G be a graph with edge set E and Cbe the set of edge sets of cycles of G. Then (E;C) is a matroid. The proof of this result is straightforward. The matroid whose existence is asserted there is called the cycle matroid of the graph G and is denoted by M(G). WebNov 14, 2016 · Jing Ma.

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.

Webcan be interpreted as the number of circuits in a certain graph N n+1 (compare also [2J). The graph Nn+l can be obtained by a certain operation from N n' and by a general theorem on circuits in oriented graphs the number of circuits of Nn+1 could be expressed in the number of circuits of N". This theorem on graphs was proved

A directed graph is called an oriented graph if none of its pairs of vertices is linked by two symmetric edges. Among directed graphs, the oriented graphs are the ones that have no 2-cycles (that is at most one of (x, y) and (y, x) may be arrows of the graph). A tournament is an orientation of a complete graph. A polytree is an orientation of an undirected tree. Sumner's conjecture states that every tournament with 2n – 2 vertices contains every polytree w… In graph theory, a part of discrete mathematics, the BEST theorem gives a product formula for the number of Eulerian circuits in directed (oriented) graphs. The name is an acronym of the names of people who discovered it: de Bruijn, van Aardenne-Ehrenfest, Smith and Tutte.
