摘要
本文研究了图的逆符号全控制数的上界。通过分析并优化点集,建立了度、奇点集、边数之间的关系,得到了图的逆符号全控制数的5个上界,并分别给出了相应的极图。
The upper bounds of the inverse signed total domination number are studied.By sets analysis and optimizing,relations between degree,odd set and size are established.Furthermore,five upper bounds of inverse signed total domination number of graphs are obtained,and the graphs satisfying these bounds are given respectively.
