Abstract
Dirac’s and Ore’s conditions (1952 and 1960) are well known and classical sufficient conditions for a graph to contain a Hamiltonian cycle and they are generalized in 1976 by the Bondy-Chvátal Theorem. In this paper, we add constraints, called conflicts. A conflict in a graph G is a pair of distinct edges of G. We denote by \((G,\mathcal {C}onf)\) a graph G with a set of conflicts \(\mathcal {C}onf\). A path without conflict P in \((G,\mathcal {C}onf)\) is a path P in G such that for any edges \(e,e'\) of P, \(\{e,e'\}\notin \mathcal {C}onf\). In this paper we consider graph with conflicts such that each vertex is not incident to the edges of more than one conflict. We call such graphs one-conflict graphs. We present sufficient conditions for one-conflict graphs to have a Hamiltonian path or cycle without conflict.
