Local strong rainbow connection number of corona product between cycle graphs
A rainbow geodesic is a shortest path between two vertices where all edges are colored differently. An edge coloring in which any pair of vertices with distance up to d, where d is a positive integer that can be connected by a rainbow geodesic is called ...

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

Hamiltonian Cycles in Strong Products of Graphs [PDF]
Abstract. Let denote the graph (k times) where is the strong product of the two graphs G and H. In this paper we prove the conjecture of J. Zaks [3]: For every connected graph G with at least two vertices there exists an integer k = k(G) for which the graph is hamiltonian.

Strong products of Kneser graphs
For a (simple, undirected) graph \(G = (V(G), E(G))\), let \(\chi(G)\) and \(\omega(G)\) denote the chromatic number and the clique number, respectively. A subgraph \(H\) of \(G\) is a retract of \(G\) iff there is an edge-preserving map \(h : V(G) \to V(H)\) with \(h(x) = x\) for all \(x \in V(H)\).

On bounds for topological descriptors of φ-sum graphs
The properties of chemical compounds are very important for the studies of the non-isomorphism phenomenon's related to the molecular graphs. Topological indices (TIs) are one of the mathematical tools which are used to study these properties.

On the (adjacency) metric dimension of corona and strong product graphs and their local variants: Combinatorial and computational results [PDF]
The metric dimension is quite a well-studied graph parameter. Recently, the adjacency metric dimension and the local metric dimension have been introduced. We combine these variants and introduce the local adjacency metric dimension.

Some Applications of Strong Product [PDF]
Let G and H be graphs. The strong product GH of graphs G and H is the graph with vertex set V(G)V(H) and u=(u1, v1) is adjacent with v= (u2, v2) whenever (v1 = v2 and u1 is adjacent with u2) or (u1 = u2 and v1 is adjacent with v2) or (u1 is adjacent ...

Theory and Applications of Fermatean Neutrosophic Graphs [PDF]
Yager et. al. defined a q-rung orthopair fuzzy sets as a new general class of Pythagorean fuzzy set in which the sum of the qth power of the support for and support against is bonded by one. Tapan et. al. extended the concept of intuitionistic fuzzy sets
