摘要
利用穷标法及分类讨论法得到了两类图W^*n+1和F^*n+1的逆符号边控制数的精确值.这里图W^*n+1表示轮图Cn∨K1的圈Cn的每个顶点上增加一条悬挂边而得到的图,图F^*n+1表示扇图Pn∨K1的路Pn的每个顶点上增加一条悬挂边而得到的图.
In this paper, we are give a exact value of inverse signed edge domination number of two classes graphs Wn+1* and Fn+1* by exhaustived method and classified discussion. Where Wn+1* denotes is a graph obtained by every vertex of Cn of wheel graph Cn∨K1 identified one pendant edge, Fn+1* denotes is a graph obtained by every vertex of Pn of Fan graph Pn∨K1 identified one pendant edge.
