Title
k-Domination stable graphs upon edge removal
Abstract
Let k be a positive integer and G = (V(G),E(G)) a graph. A subset S of V(G) is a k-dominating set if every vertex of V(G) - S is adjacent to at least k vertices of S. The k-domination number gamma(k) (G) is the minimum cardinality of a k-dominating set of G. A graph G is called gamma(-)(k)-stable if gamma(k)(G - e) = gamma(k)(G) for every edge e of E(C). We first give a necessary and sufficient condition for gamma(-)(k)-stable graphs. Then for k >= 2 we provide a constructive characterization of gamma(-)(k)-stable trees.
