On weakly connected domination in graphs II

open access: yesDiscrete Mathematics, 2005
A dominating set D is a weakly connected dominating set of a connected graph G=(V,E) if (V,E∩(D×V)) is connected. The weakly connected domination number of G, denoted γwc(G), is min{|S||S is a weakly connected dominating set of G}. We characterize graphs

Connected domination value in graphs [PDF]

open access: yesElectronic Journal of Graph Theory and Applications, 2021
In a connected graph G = (V,E), a set D ⊂ V is a connected dominating set if for every vertex v ∈ V \ D, there exists u ∈ D such that u and v are adjacent, and the subgraph〈D〉induced by D in G is connected.

On graphs with equal domination and connected domination numbers

open access: yesDiscrete Mathematics, 1999
In this paper we characterize the class of trees, unicyclic graphs and cubic graphs for which the domination number is equal to the connected domination ...

On graphs for which the connected domination number is at most the total domination number

open access: yesDiscrete Applied Mathematics, 2012
In this note, we give a finite forbidden subgraph characterization of the connected graphs for which any non-trivial connected induced subgraph has the property that the connected domination number is at most the total domination number. This question is

Connected cototal domination number of a graph [PDF]

open access: yesTransactions on Combinatorics, 2012
A dominating set $D subseteq V$ of a graph $G = (V,E)$ is said to be a connected cototal dominating set if $langle D rangle$ is connected and $langle V-D rangle neq phi$, contains no isolated vertices.

Making a Dominating Set of a Graph Connected

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let G = (V,E) be a graph and S ⊆ V. We say that S is a dominating set of G, if each vertex in V \ S has a neighbor in S. Moreover, we say that S is a connected (respectively, 2-edge connected or 2-connected) dominating set of G if G[S] is connected ...

On weakly connected domination in graphs

open access: yesDiscrete Mathematics, 1997
A weakly connected dominating set for a connected graph is a dominating set D of vertices of the graph such that the edges not incident to any vertex in D do not separate the graph.

Connected Domination in Plane Triangulations

open access: yesInvolve, a Journal of Mathematics
A set of vertices of a graph $G$ such that each vertex of $G$ is either in the set or is adjacent to a vertex in the set is called a dominating set of $G$.
