Edge Colouring of Neutrosophic Graphs and Its Application in Detection of Phishing Website
Discrete Dynamics in Nature and Society, 2022 Graph colouring enjoys many practical as well as theoretical uses. Graph colouring is still a very active subject of research. This article introduces a new concept of the chromatic number of the neutrosophic graph (NG).

A new approach to fuzzy group theory using (𝛼, 𝛽) -Pythagorean fuzzy sets [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 A Pythagorean fuzzy set (PFS) is a very efficient and powerful tool for handling uncertainty and vagueness. In this paper, we present the notion of (𝛼, 𝛽) -Pythagorean fuzzy set (PFS) as a generalisation of Pythagorean fuzzy set (PFS). We propose a new

An investigation of edge F-index on fuzzy graphs and application in molecular chemistry
Complex & Intelligent Systems, 2022 The molecular descriptors are a useful tool in the spectral graph, molecular chemistry and several fields of chemistry and mathematics. The edge F-index is proposed for fuzzy graphs (FGs) here. Bounds of this index are calculated for FGs. The FG has been

The Reformulated F-Index of Vertex and Edge F-Join of Graphs
Journal of Chemistry, 2022 The valency based topological indices (TIs) are defined by algebraic functions as the chemical graph theory tools in which the structural parameters are used as input and the output is related with the topology of chemical species.

On the Reformulated Second Zagreb Index of Graph Operations
Journal of Chemistry, 2021 Topological indices (TIs) are expressed by constant real numbers that reveal the structure of the graphs in QSAR/QSPR investigation. The reformulated second Zagreb index (RSZI) is such a novel TI having good correlations with various physical attributes,

On the Inverse Problem for Some Topological Indices
Journal of Mathematics, 2021 The study of the inverse problem (IP) based on the topological indices (TIs) deals with the numerical relations to TIs. Mathematically, the IP can be expressed as follows: given a graph parameter/TI that assigns a non-negative integer value g to every ...

Mathematics, 2023 A fuzzy graph G is stated to have a set of trees as its tree cover if all the vertices of G are in their union. The maximum weight tree in the tree cover is assumed to be the cost of a tree cover for a fuzzy graph.
