爪心独立图的模k泛圈性

Pancyclicity Mod k of Claw-Center-Independent Graph

证明了2-连通的爪心独立图G,如果对任意的非爪心点v,有d(v)≥k+1,对任意的爪心点u,存在v∈N(u),使得d(v)≥k+2,那么G是模k点泛圈的.

If G is a 2-cormected claw-center-independent graph, every non-claw-center vertex v satisfies d （v） ≥ k ＋ 1, there is ∈ E N（ u ） such that d （ v ） ≥ k ＋ 2 for every claw-center vertex u, then G is vertex-pancylic mod k.
