In this paper we introduce the concept of signed tree domination in graphs,we obtain a upper bound and a lower bound of signed tree domination numbers for general graphs G,and show that the two bounds are best possible.
引入了图的符号树控制的概念,给出一个连通图G的符号树控制数γ′T(G)的一个上界和一个下界,说明了这两个界限均是最好可能的,并确定几类特殊图的符号树控制数,这包括了圈、轮图、完全图和完全二部图。
