摘要
引入了图的好符号星控制的概念,求出了欧拉图、完全二部图、完全图和轮图的好符号星控制数,并改进了图的符号星控制数的两个上界.
In this paper we introduce the concept of good signed star domination in graphs ,find the good signed star domination numbers of Euler graph;complete bipartite graph;complete graph and wheel graph,improve two upper bounds of the signed star domination numbers of graphs.
