On the strong metric dimension of corona product graphs and join graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2013
Let $G$ be a connected graph. A vertex $w$ strongly resolves a pair $u$, $v$ of vertices of $G$ if there exists some shortest $u-w$ path containing $v$ or some shortest $v-w$ path containing $u$. A set $W$ of vertices is a strong resolving set for $G$ if every pair of vertices of $G$ is strongly resolved by some vertex of $W$.

Fork-decomposition of strong product of graphs [PDF]

open access: yesRatio Mathematica, 2023
Decomposition of arbitrary graphs into subgraphs of small size is assuming importance in the literature. There are several studies on the isomorphic decomposition of graphs into paths, cycles, trees, stars, sunlet etc.

Strong Edge Coloring of Cayley Graphs and Some Product Graphs [PDF]

open access: yesGraphs and Combinatorics, 2022
AbstractA strong edge coloring of a graph G is a proper edge coloring of G such that every color class is an induced matching. The minimum number of colors required is termed the strong chromatic index. In this paper we determine the exact value of the strong chromatic index of all unitary Cayley graphs.

Gromov Hyperbolicity in Strong Product Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2013
If X is a geodesic metric space and $x_1,x_2,x_3\in X$, a geodesic triangle $T=\{x_1,x_2,x_3\}$ is the union of the three geodesics $[x_1x_2]$, $[x_2x_3]$ and $[x_3x_1]$ in $X$. The space $X$ is $\delta$-hyperbolic $($in the Gromov sense$)$ if any side of $T$ is contained in a $\delta$-neighborhood of the union of the two other sides, for every ...

Bounding the Open k-Monopoly Number of Strong Product Graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let G = (V, E) be a simple graph without isolated vertices and minimum degree δ, and let k ∈ {1 − ⌈δ/2⌉, . . . , ⌊δ/2⌋} be an integer. Given a set M ⊂ V, a vertex v of G is said to be k-controlled by M if δM(v)≥δG(v)2+k$\delta _M (v) \ge {{\delta _G (v)}

Computing FGZ Index of Sum Graphs under Strong Product [PDF]

open access: yesJournal of Mathematics, 2021
Topological index (TI) is a function that assigns a numeric value to a (molecular) graph that predicts its various physical and structural properties. In this paper, we study the sum graphs (S-sum, R-sum, Q-sum and T-sum) using the subdivision related ...

On global (strong) defensive alliances in some product graphs [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2017
A defensive alliance in a graph is a set $S$ of vertices with the property that every vertex in $S$ has at most one more‎ ‎neighbor outside of $S$ than it has inside of $S$‎. ‎A defensive alliance $S$ is called global if it forms a dominating set‎. ‎The

The geodetic number of strong product graphs [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2010
For two vertices u and v of a connected graph G, the set IG[u; v] consists of all those vertices lying on u v geodesics in G. Given a set S of vertices of G, the union of all sets IG[u; v] for u; v 2 S is denoted by IG[S]. A set S V (G) is a geodetic set if IG[S] = V (G) and the minimum cardinality of a geodetic set is its geodetic number g(G) of G ...
