    On stability of the hamiltonian index under contractions and closures

  • Original language description

    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

    Stabilita hamiltonovského indexu při kontrakcích a uzávěrech

  • Czech description

    Hamiltonovský index grafu G je definován jako nejmenší přirozené číslo k, pro které je k-tý iterovaný hranový graf grafu G hamiltonovský. V článku nejprve ukazujeme, že, s jednou výjimkou, přidání hrany do grafu nemůže zvýšit jeho hamiltonovský index. Te
