##### 7. Domination number of complements of functigraphs

Volume 10, Issue 01 , Winter 2021, Pages 71-78

##### Abstract
Let $G=(V, E)$ be a simple graph. A subset $S \subseteq V(G)$ is a \textit{dominating set} of $G$ if every vertex in $V(G) \setminus S$ is adjacent to at least one vertex in $S.$ The \textit{domination number} of graph $G,$ denoted by $\gamma(G),$ is the minimum size of a dominating set of vertices $V(G).$ ...  Read More
