图的强符号全控制数有着许多重要的应用背景,因而确定其下界有重要的意义.本文提出了图的强符号全控制数的概念,在构造适当点集的基础上对其进行了研究,给出了:(1)一般图的强符号全控制数的5个独立可达的下界及达到其界值的图;(2)确定了圈、轮图、完全图、完全二部图的强符号全控制数的值.
圖的彊符號全控製數有著許多重要的應用揹景,因而確定其下界有重要的意義.本文提齣瞭圖的彊符號全控製數的概唸,在構造適噹點集的基礎上對其進行瞭研究,給齣瞭:(1)一般圖的彊符號全控製數的5箇獨立可達的下界及達到其界值的圖;(2)確定瞭圈、輪圖、完全圖、完全二部圖的彊符號全控製數的值.

The strong signed total domination number of a graph has its important applying background, so it is useful to investigate the bounds of it. In this paper we point out the concept of the strong signed total domination number of a graph and research based on construction of suitable vetex sets. We obtain: (1) the five sharp lower bounds of the strong signed total domination number of a general graph and some graphs which attain these lower bounds respectively. (2) the exact values of the strong signed total domination number of a cycle graph, a wheel graph, a complete graph, a complete bipartite graph and so on.
