Polyhedra associated with locating-dominating, open locating-dominating and locating total-dominating sets in graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2022
International audienceThe problems of determining locating-dominating, open locating-dominating or locating total-dominating sets of minimum cardinality in a graph G are variations of the classical minimum dominating set problem in G and are all known to

Total Dominating Sets in Maximal Outerplanar Graphs [PDF]

open access: possibleGraphs and Combinatorics, 2017
A set \(D\subseteq V(G)\) is a total domination set of graph \(G\) if every vertex from \(V(G)\) has a neighbor in \(D\). The minimum cardinality of a total domination set of \(G\) is called total domination number and is denoted by \(\gamma_t(G)\). A recent result from \textit{M. Dorfling} et al. [Discrete Math. 339, No.

INTERIOR TOTAL DOMINATING SETS IN GRAPHS

Advances and Applications in Discrete Mathematics, 2018
Summary: Let \(G = (V(G)\), \(E(G))\) be a simple graph. A total dominating set \(D\) of \(V(G)\) is an interior total dominating set of \(G\) if every \(v\in D\) is an interior vertex of \(G\). The minimum cardinality of an interior total dominating set of \(G\), denoted by \(\gamma_{lt}(G)\) is called an interior total domination number of \(G\).

Total Dominating Set Games

2005
In this paper, we consider cooperative games arising from total domination problem on graphs. We introduce two games, rigid total dominating set game and relaxed total dominating set game, and focus on their cores. First, a common necessary and sufficient condition for the balancedness of the two total dominating set games is obtained.

On the Number of Minimum Total Dominating Sets in Trees

Journal of Applied and Industrial Mathematics, 2023
Summary: The minimum total dominating set (MTDS) of a graph is a vertex subset \(D\) of minimum cardinality such that every vertex of the graph is adjacent to at least one vertex of \(D\). In this paper we obtain the sharp upper bound for the number of MTDS in the class of \(n\)-vertex 2-caterpillars.

Approximation for minimum total dominating set

Proceedings of the 2nd International Conference on Interaction Sciences: Information Technology, Culture and Human, 2009
A total dominating set is a dominating set which induces a subgraph without isolated vertices. In this paper, we study the approximation of minimum total dominating set problem. First, we present a new analysis for one-step greedy algorithm with approximation ratio ln(δ-0.5)+1.5, where δ is the maximum degree of the given graph.

Linear Separation of Total Dominating Sets in Graphs

2013
A total dominating set in a graph is a set of vertices such that every vertex of the graph has a neighbor in the set. We introduce and study graphs that admit non-negative real weights associated to their vertices so that a set of vertices is a total dominating set if and only if the sum of the corresponding weights exceeds a certain threshold. We show
