F index of graphs based on four new operations related to the strong product
AKCE International Journal of Graphs and Combinatorics, 2020 For a molecular graph, the first Zagreb index of a graph is equal to the sum of squares of the vertex degrees of the graph and the forgotten topological index (F-index) of a graph is defined as the sum of cubes of the vertex degrees of the graph.

Some Applications of Strong Product [PDF]
Mathematics Interdisciplinary Research, 2018 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 ...

ON THE STRONG DOMINATING SETS OF GRAPHS [PDF]
Journal of Algebraic Systems, 2023 Let $G=(V(G),E(G))$ be a simple graph. A set $D\subseteq V(G)$ is a strong dominating set of $G$, if for every vertex $x\in V(G)\setminus D$ there is a vertex $y\in D$ with $xy\in E(G)$ and $deg(x)\leq deg(y)$. The strong domination number $\gamma_{st}(G)

On bounds for topological descriptors of φ-sum graphs
Journal of Taibah University for Science, 2020 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.

A study on vague-valued hesitant fuzzy graph with application
Frontiers in Physics, 2022 The hesitant fuzzy graph (HFG) is one of the most powerful tools to find the strongest influential person in a network. Many problems of practical interest can be modeled and solved by using HFG algorithms.

An exploratory study on the links between individual upcycling, product attachment and product longevity [PDF]
, 2015 Product attachment, the emotional bond experienced with a product, is an emerging concept for sustainable production and consumption. The logic behind it is that when people are attached to any product, they are more likely to handle the product with ...

Complex Vague Graphs and Their Application in Decision-Making Problems
IEEE Access, 2020 Fuzzy graph models are found everywhere in natural and human made structures, including process dynamics in biological, physical and social systems. Since real-life problems are often uncertain due to inconsistent and indeterminate information, it is ...

New concepts on level graphs of vague graphs with application in medicine
Frontiers in Physics, 2023 Vague graphs (VGs), belonging to the fuzzy graph (FG) family, have good capabilities when facing problems that cannot be expressed by FGs. When an element membership is unclear, neutrality is a good option that can be well-supported by a VG. The previous

Total irregularity strength for product of two paths
AKCE International Journal of Graphs and Combinatorics, 2020 In this paper we define a totally irregular total labeling for Cartesian and strong product of two paths, which is at the same time vertex irregular total labeling and also edge irregular total labeling.
