Abstract

Let $G=V(G),E(G)$ be a graph. A complementary signed edge dominating function $(CSEDF)$ of G is a function $ g: E(G)\rightarrow\{-1,+1\} $ such that $\sum{_{e{^{'}}\notin N[e]}} {g(e^{'})} \geq 1 ,$ for every $e\in E(G)$. Weight of a CSEDF g is defined as $w(g)= \sum{_{e \in E(G)}} {g(e)}$. The complementary signed edge domination number of G is defined as $ \gamma{^{'}}_{cs} {(G)} = min \{ w(g)$ $|$ g is a CSEDF of G\}. In this paper, the complementary signed edge domination number for some graphs are found.
