关于$(P_5,\bar{P_5})$ -稀疏图及其它图族
On $(P_5,\bar{P_5})$-sparse graphs and other families
摘要:
我们扩展了以前由{ \scshape Hoàng}引入的$P_4$ -稀疏图的概念,考虑了$\mathcal{F}$ -稀疏图,其中$\mathcal{F}$表示$p$顶点上的有限图集。因此我们得到了关于$(P_5,\bar{P_5})$ -稀疏图的一些结果,这些结果是关于$(P_5,\bar{P_5})$ -free图的已知结果.最后,我们完整地描述了$(P_5,\bar{P_5}, bull$)-稀疏图的结构,从而得出这些图具有有界的圈宽。
英文摘要:
We extend the notion of $P_4$-sparse graphs previously introduced by {\scshape Hoàng} by considering $\mathcal{F}$-sparse graphs were $\mathcal{F}$ denotes a finite set of graphs on $p$ vertices. Thus we obtain some results on $(P_5,\bar{P_5})$-sparse graphs already known on $(P_5,\bar{P_5})$-free graphs. Finally we completely describe the structure of $(P_5,\bar{P_5}, bull$)-sparse graphs, it follows that those graphs have bounded clique-width.
