摘要 引入了关于图的符号路(点)控制概念,给出了对于任何一棵非平凡树T的符号路(点)控制数γP(G)的一个下界,即γP(T)≥1,又获得了满足γP(G)=V(G)的所有连通图一个特征。此外,还确定了圈的符号路(点)控制数。 Introducing the concept of signed path(vertex) domination in graphs,and give a lower bound for signed path(vertex) domination numberγPGof every a non-trivial tree T,γPT≥1,and gain a feature for all connected graphs of γPG=VG.In addition,get the signed path(vertex) domination number for the cycle.
