Dominating sets whose closed stars form spanning trees
For a subset W of vertices of an undirected graph G, let S(W ) be the subgraph consisting of W , all edges incident to at least one vertex in W , and all vertices adjacent to at least one vertex in W . If there exists a W such that S(W ) is a tree containing all the vertices of G, then S(W ) is a spanning star tree of G. These and associated notions are related to connected and/or acyclic domin...
متن کاملTrees having many minimal dominating sets
We disprove a conjecture by Skupień that every tree of order n has at most 2 minimal dominating sets. We construct a family of trees of both parities of the order for which the number of minimal dominating sets exceeds 1.4167. We also provide an algorithm for listing all minimal dominating sets of a tree in time O(1.4656). This implies that every tree has at most 1.4656 minimal dominating sets.
متن کاملMinimal 2-dominating sets in trees
We provide an algorithm for listing all minimal 2-dominating sets of a tree of order n in time O(1.3248n). This implies that every tree has at most 1.3248n minimal 2-dominating sets. We also show that this bound is tight.
متن کاملTrees with unique minimum total dominating sets
A set S of vertices of a graph G is a total dominating set if every vertex of V (G) is adjacent to some vertex in S. We provide three equivalent conditions for a tree to have a unique minimum total dominating set and give a constructive characterization of such trees.
متن کاملMinimal Double Dominating Sets in Trees
We provide an algorithm for listing all minimal double dominating sets of a tree of order n in time O(1.3248). This implies that every tree has at most 1.3248 minimal double dominating sets. We also show that this bound is tight.
