چکیده | ||
In this paper, we define the common minimal common neighborhood dominating signed graph (or common minimal $CN$-dominating signed graph) of a given signed graph and offer a structural characterization of common minimal $CN$-dominating signed graphs. In the sequel, we also obtained switching equivalence characterization: $\overline{\Sigma} \sim CMCN(\Sigma)$, where $\overline{\Sigma}$ and $CMCN(\Sigma)$ are complementary signed graph and common minimal $CN$-signed graph of $\Sigma$ respectively. | ||
