Path 3-(edge-)connectivity of lexicographic product graphs
Discrete Applied Mathematics, 2020This paper studies path 3-connectivity \(\pi_3\) and path 3-edge-connectivity \(\omega_3\) of lexicographic product graphs. If \(G\) is a 2-connected graph and \(H\) is a graph with \(n\) vertices, it is shown that \(\pi_3(G\circ H)\ge n\). Moreover, \(\omega_3(G\circ H)\ge3\lfloor n/2\rfloor\) if \(n\) is even while \(\omega_3(G\circ H)\ge3\lfloor n/2\

Coupon coloring of lexicographic product of graphs
The Art of Discrete and Applied Mathematics, 2022Summary: A \(k\)-coupon coloring of a graph \(G\) without isolated vertices is an assignment of colors from \([k]=\{1,2,\dots,k\}\) to the vertices of \(G\) such that the neighborhood of every vertex of \(G\) contains vertices of all colors from \([k]\).

[1, k]-Domination Number of Lexicographic Products of Graphs
Bulletin of the Malaysian Mathematical Sciences Society, 2020Let \(G = (V, E)\) be a graph. Let \(k\) be a positive integer. A subset \(D\) of vertices of a graph \(G\) is \([1, k]\)-dominating if every vertex not in \(D\) can have at least one neighbor in \(D\) and at most \(k\) neighbors in \(D\). \(\gamma_{[1,k]}(G)\) denotes the cardinality of a smallest \([1, k]\)-dominating set. A \([1, k]\)-dominating set

SECURE DOMINATING SETS IN THE LEXICOGRAPHIC PRODUCT OF GRAPHS
Advances and Applications in Discrete Mathematics, 2019Summary: Let \(G=(V(G), E(G))\) be a simple graph. A set \(S\subseteq V(G)\) is a dominating (total dominating) set of \(G\) if for every \(v\in V(G)\backslash S\) (resp. \(v\in V(G)\)), there exists \(u\in S\) such that \(uv\in E(G)\). A dominating (total dominating) set \(S\) of \(G\) is a secure dominating (resp. secure total dominating) set of \(G\)

Path-connectivity of lexicographic product graphs
International Journal of Computer Mathematics, 2014Dirac showed that in a -connected graph there is a path through all the k vertices. The k-path-connectivity of a graph G, which is a generalization of Dirac's notion, was introduced by Hager in 1986. Denote by the lexicographic product of two graphs G and H. In this paper, we prove that for any two connected graphs G and H. Moreover, the

Omega Indices of Strong and Lexicographic Products of Graphs
Current Organic SynthesisBackground: The degree sequence of a graph is the list of its vertex degrees arranged in usually increasing order. Many properties of the graphs realized from a degree sequence can be deduced by means of a recently introduced graph invariant called omega invariant.
