Secure Total Domination in Rooted Product Graphs

open access: yesMathematics, 2020
In this article, we obtain general bounds and closed formulas for the secure total domination number of rooted product graphs. The results are expressed in terms of parameters of the factor graphs involved in the rooted product.

Total Domination in Rooted Product Graphs [PDF]

open access: yesSymmetry, 2020
During the last few decades, domination theory has been one of the most active areas of research within graph theory. Currently, there are more than 4400 published papers on domination and related parameters. In the case of total domination, there are over 580 published papers, and 50 of them concern the case of product graphs.

Total Roman Domination Number of Rooted Product Graphs [PDF]

open access: yesMathematics, 2020
Let G be a graph with no isolated vertex and f:V(G)→{0,1,2} a function. If f satisfies that every vertex in the set {v∈V(G):f(v)=0} is adjacent to at least one vertex in the set {v∈V(G):f(v)=2}, and if the subgraph induced by the set {v∈V(G):f(v)≥1} has ...

On Metric Dimensions of Symmetric Graphs Obtained by Rooted Product

open access: yesMathematics, 2018
Let G = (V, E) be a connected graph and d(x, y) be the distance between the vertices x and y in G. A set of vertices W resolves a graph G if every vertex is uniquely determined by its vector of distances to the vertices in W.

The Independence Polynomial of Rooted Products of Graphs

open access: yesDiscrete Applied Mathematics, 2010
A stable (or independent) set in a graph is a set of pairwise nonadjacent vertices thereof. The stability number \(\alpha(G)\) is the maximum size of stable sets in a graph \(G\). The independence polynomial of \(G\) is \[ I(G;x) = \sum_{k=0}^{\alpha(G)} s_kx^k= s_0+s_1x+s_2x^2+\cdots+ s_{\alpha(G)} x^{\alpha(G)} \quad (s_0:=1), \] where \(s_k\) is the

Bounds on the Twin-Width of Product Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Twin-width is a graph width parameter recently introduced by Bonnet, Kim, Thomass\'{e} & Watrigant. Given two graphs $G$ and $H$ and a graph product $\star$, we address the question: is the twin-width of $G\star H$ bounded by a function of the twin ...

The study of line graphs of subdivision graphs of some rooted product graphs via K-Banhatti indices

open access: yesInternational Journal of Mathematics for Industry, 2023
The degree-based topological indices are numerical graph invariants that are used to link a molecule’s structural characteristics to its physical, and chemical characteristics.
