摘要
拟无爪图是比无爪图更广泛的图类.证明如下结论:(i)顶点数n≥3的连通、局部连通的拟无爪图是完全圈可扩的;(ii)若G2是顶点数n≥3的连通的拟无爪图,则G2是完全圈可扩的.这些结论推广了无爪图及拟无爪图中的相应结论.
In this paper, we prove the following result:
(i) A connected, locally connected quasi - claw - free graph of order n≥ 3 is fully cycle extendable ;
(ii) if G2 is connected quasi - claw - free graph of order n ≥ 3 , then G^2 is fully cycle extendable. These results extend the corresponding results in claw -free graph.
