| The concept of domination stability in graphs was introduced in 1983 by Bauer, Harary, Nieminen and Suffel and has been further studied by Nader Jafari Rad, Elahe Sharifi, Marcin Krzywkowski. The $\gamma^+$-stability of $G$, denoted by $\gamma^+(G)$, is the minimum number of vertices whose removal from $G$ increases the domination number. The $\gamma^-$-{\it stability} of $G$, denoted by $\gamma^-(G)$, is the minimum number of vertices whose removal from $G$ decreases the domination number. The {\it domination stability} of $G$, denoted by $st_\gamma(G)$, is the minimum number of vertices whose removal changes the domination number. In this paper the concept of domination stability is extended to $m$-eternal domination. {\it Eternal domination} of a graph requires the vertices of a graph to be protected, against infinitely long sequences of attacks, by guards located at vertices (at most one guard in each vertex), and a guard must move from a neighboring vertex to an attacked vertex with the requirement that the configuration of guards induces a dominating set at all times. Two models of the problem, one in which only one guard moves at a time and one in which more than one guard may move simultaneously are studied in the literature. The model of eternal domination in which more than one guard move simultaneously is called the $m$-eternal domination. The $m$-eternal domination number, $\gamma_m^\infty(G)$ of a graph $G$ is the minimum number of guards needed to defend $G$ against any such sequence of attacks. | ||
