3)reverse signed star domination number反符号星控制数
1.Let G=(V,E) be a graph without isolated vertices,a function:f:E→{+1,-1} is said to be a reverse signed star domination function(RSSDF) of G if ∑f(e)≤0 holds for every v∈V(G),where e is the edge of the star which v belongs to,and γ′rss(G)=max{∑f(e)|f is an RSSDF of G,e∈E(G)} is called thereverse signed star domination number of G.而γr′ss(G)=max{∑f(e)|f为图G的反符号星控制函数,e∈E(G)}称为图G的反符号星控制数。

5)reverse signed star domination function反符号星控制函数
1.Let G=(V,E) be a graph without isolated vertices,a function:f:E→{+1,-1} is said to be areverse signed star domination function(RSSDF) of G if ∑f(e)≤0 holds for every v∈V(G),where e is the edge of the star which v belongs to,and γ′rss(G)=max{∑f(e)|f is an RSSDF of G,e∈E(G)} is called the reverse signed star domination number of G.引入了图的反符号星控制的概念,设G=(V,E)是一个没有孤立点的图,一个函数f:E→{+1,-1}对一切点v∈V(G)所在的星中的边e有∑f(e)≤0成立,则称f为图G的一个反符号星控制函数。
