In graph theory, a cycle graph , sometimes simply known as an -cycle (Pemmaraju and Skiena 2003, p. 248), is a graph on nodes containing a single cycle through all nodes. A different sort of cycle graph, here termed a group cycle graph, is a graph which shows cycles of a group as well as the connectivity between the group … WebCycle graphs are used as a pedagogical tool in Nathan Carter's 2009 introductory textbook Visual Group Theory.

WebOct 3, 2006 · Abstract. Let G = (X, Y, E) be a bipartite graph with X = Y = n. Chvátal gave a condition on the vertex degrees of X and Y which implies that G contains a Hamiltonian cycle. It is proved here ... A cycle graph is: • 2-edge colorable, if and only if it has an even number of vertices • 2-regular • 2-vertex colorable, if and only if it has an even number of vertices. More generally, a graph is bipartite if and only if it has no odd cycles (Kőnig, 1936). themed wordlists
