Abstract
A graph G with p≥3 points, 0≤n≤p−3, is called n-Hamiltonian if the removal of any k points from G, 0≤k≤n, results in a Hamiltonian graph. This generalizes the concept of Hamiltonian graphs in as much as the 0-Hamiltonian graphs are precisely the Hamiltonian graphs. Sufficient conditions for a graph to be n-Hamiltonian are presented, including generalizations of results on Hamiltonian graphs due to Dirac, Ore, and Pósa.
