Abstract

A dominating set D V ( G ) is a weakly connected dominating set in G if the subgraph G [ D ] w = ( N G [ D ] , E w ) weakly induced by D is connected, where E w is the set of all edges having at least one vertex in D . Weakly connected domination number γ w ( G ) of a graph G is the minimum cardinality among all weakly connected dominating sets in G . A graph G is said to be weakly connected domination stable or just γ w -stable if γ w ( G ) = γ w ( G + e ) for every edge e belonging to the complement G ¯ of G . We provide a constructive characterization of weakly connected domination stable trees.

AB - A dominating set $D\subseteq V(G)$ is a weakly connected dominating set in $G$ if the subgraph $G[D]_w=(N_G[D],E_w)$ weakly induced by $D$ is connected, where $E_w$ is the set of all edges having at least one vertex in $D$. Weakly connected domination number$\gamma _w(G)$ of a graph $G$ is the minimum cardinality among all weakly connected dominating sets in $G$. A graph $G$ is said to be weakly connected domination stable or just $\gamma _w$-stable if $\gamma _w(G)=\gamma _w(G+e)$ for every edge $e$ belonging to the complement $\overline{G}$ of $G.$ We provide a constructive characterization of weakly connected domination stable trees.
