Nous prouvons une conjecture due & Bondy et Fan. Un cycle C d'un graphe G est dit m-dominant si tout sommet de V(G -C) est a distance au plus m de C. Notre r&t&at est: si G est k-connexe, et si G n'a pas de cycle m-dominant, alors il existe un stable de cardinal k + 1, dont les sommets sont deux 3 d
if G is a directed graph with n vertices and minimal outdegree k, then G contains a directed cycle of length at most In~k]. This conjecture is known to be true for k ~< 3. In this paper, we present a proof of the conjecture for the cases k = 4 and k = 5. We also present a new conjecture which implie
AnSTRACr. Let G be a graph, and let v be a vertex of G. We denote by N(v) the set of vertices of G which are adjacent to v, and by (N(v)) the subgraph of G induced by N(v). We call <N(v)) the neighborhood of v. In a paper of 1968, Agakishieva has, as one of her main theorems, the statement: "Graphs
