%0 Journal Article %T On $(P_5,\bar{P_5})$-sparse graphs and other families %A Jean-Luc Fouquet %A Jean-Marie Vanherpe %J Computer Science %D 2008 %I arXiv %X We extend the notion of $P_4$-sparse graphs previously introduced by {\scshape Ho\`ang} 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. %U http://arxiv.org/abs/0803.2135v1
