摘要 引入了图的符号边全控制的概念,主要刻划了满足sγt′(G)=|E(G)|且δ(G)2的所有连通图G,给出了n阶k-正则图G的符号边全控制数γst′(G)的下限,确定所有轮图的符号边全控制数,最后还提出了一个关于sγ′t(G)上界的猜想. In this paper we introduce the concept of signed edge total domination number γ′st(G) of a graph G, characterize all connected graphs with δ(G) ≥2 and γ′st(G)=|E(G)|. obtain a lower bound of γ′st(G) for all k-regular graphs of order n, and determine the exact value of γ′st ( Wn + 1 ) of for all wheels Wn + 1, In addition, we pose a conjecture about the upper bound of γ′st (G).
