Bounds on the Exponential Domination Number

open access: greenDiscrete Mathematics, 2015
As a natural variant of domination in graphs, Dankelmann et al. [Domination with exponential decay, Discrete Math. 309 (2009) 5877-5883] introduce exponential domination, where vertices are considered to have some dominating power that decreases exponentially with the distance, and the dominated vertices have to accumulate a sufficient amount of this ...

Game domination number

open access: yesDiscrete Mathematics, 2002
The dominating set of a digraph \(D\) is a set \(S\) of vertices such that for every \(v\not\in S\) there exists \(u\in S\) with \(uv\in A(D)\). The domination number of \(D\) is the cardinality of the smallest dominating set. The game domination number of an undirected graph \(G\) is the domination number of the digraph \(D\) obtained as a result of ...

Hop Domination in Graphs-II

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
Let G = (V;E) be a graph. A set S ⊂ V (G) is a hop dominating set of G if for every v ∈ V - S, there exists u ∈ S such that d(u; v) = 2. The minimum cardinality of a hop dominating set of G is called a hop domination number of G and is denoted by γh(G ...

Domination Subdivision Numbers

open access: yesDiscussiones Mathematicae Graph Theory, 2001
A set \(S\) of vertices of a graph \(G\) is a dominating set if every vertex of \(V(G)-S\) is adjacent to some vertex in \(S\). The domination number \(\gamma(G)\) is the minimum cardinality of a dominating set of \(G\), and the domination subdivision number \(\text{sd}_{\gamma}(G)\) is the minimum number of edges that must be subdivided (each edge in \

On resolving domination number of special family of graphs

open access: yesJournal of Physics: Conference Series, 2020
Let G be a simple, finite, and connected graph. A dominating set D is a set of vertices such that each vertex of G is either in D or has at least one neighbor in D.

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.

Resolving domination number of helm graph and it’s operation

open access: yesJournal of Physics: Conference Series, 2020
Let G be a connected graph. Dominating set is a set of vertices which each vertex D has at least one neighbor in G. The minimum cardinality of D is called the domination number G(γ(G)).

The geodetic domination number of comb product graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2020
A subset S of vertices in graph G is called a geodetic set if every vertex in V(G) \ S lies on a shortest path between two vertices in S. A subset S of vertices in G is called a dominating set if every vertex in V(G) \  S is adjacent to a vertex in S ...
