摘要
文[2]证明了每个连通,N_2——局部连通,无爪、又δ≥2,且不含同构于G_1或 G_2的导出子图的图具有圈扩张性。本文在同样前题下,在含导出于图 G_1、G_2时得具有[2]中结论的一类图。
In[2],a kind of graph with cyclic extensibility which conneted,N_2—locally connect- ed,δ≥2 and not cortained graphs G_1 G_2 is given.Following,under the conditions of theo- roms in [2],a kind of graph with cyclic extensibility which contained induced graphs G_1 G_2 is given.
