英文摘要 | Let G be a 2-connected graph on n vertices and delta be the minimum degree of G( V, E). Set NC = min{/N(u) boolean OR N(v)/ : u, v epsilon V, uv is not an element of E}. In this paper, we show that if for any independent set {u, v, w} of G, we have min{/N(u) boolean OR N(v)/ + d(w), /N(u) boolean OR N(w)/ + d(v), /N(v) boolean OR N(w)/ + d(u)} greater than or equal to n + 1, then for any integer 7 less than or equal to i less than or equal to n and any vertices x,y such that {x, y} is not a cut vertex set of G, there exists a path connecting u, v with i vertices in G. In particular, if G is 3-connected, then G is [7,n]-panconnected. Using this result, we can prove that if NC + delta greater than or equal to n + 1, then G is vertex pancyclic. This was conjectured by Faudree, Gould, Jacobson and Lesniak. |
