It contains a graph whose edges and vertices are assigned values, and that corresponds to the Hamiltonian matrix of the model being simulated. In Kwant the creation of the system is separated from its use in numerical calculations. First an instance of the Builder class is used to ...
WebIn 1973, Chartrand [2] introduced the hamiltonian index of a connected graph G that is not a path to be the minimum number of applications of the line graph operator so that the resulting graph is hamiltonian. He showed that the hamiltonian index exists as a finite number. In 1983, Clark and Wormald [3] extended this idea of Chartrand and Web1 de jun. de 2005 · The hamiltonian index of a graph G is the smallest integer k such that the k‐th iterated line graph of G is hamiltonian. We first show that, with one exceptional case, adding an edge to a graph cannot increase its hamiltonian index. We use this result to prove that neither the contraction of an AG(F)‐contractible subgraph F of a graph G …
