Solutions of Detour Distance Graph Equations

open access: yesSensors, 2022
Graph theory is a useful mathematical structure used to model pairwise relations between sensor nodes in wireless sensor networks. Graph equations are nothing but equations in which the unknown factors are graphs.

Application of Graph Theory for Identifying Connectivity Patterns in Human Brain Networks: A Systematic Review

open access: yesFrontiers in Neuroscience, 2019
Background: Analysis of the human connectome using functional magnetic resonance imaging (fMRI) started in the mid-1990s and attracted increasing attention in attempts to discover the neural underpinnings of human cognition and neurological disorders. In

Generalized inverses in graph theory

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
–In this article, some interesting applications of generalized inverses in the graph theory are revisited. Interesting properties of generalized inverses are employed to make the proof of several known results simpler, and several techniques such as ...

On the Beta-Number of Forests with Isomorphic Components

open access: yesDiscussiones Mathematicae Graph Theory, 2018
The beta-number, β (G), of a graph G is defined to be either the smallest positive integer n for which there exists an injective function f : V (G) → {0, 1, . . .

Comparative Study of Prism Octahedron Network via Eccentric Invariants

open access: yesJournal of Chemistry, 2023
Topological indices are empirical features of graphs that characterize the topology of the graph and, for the most part, are graph independent. An important branch of graph theory is chemical graph theory.

A method in graph theory

open access: yesDiscrete Mathematics, 1976
AbstractA unified approach to a variety of graph-theoretic problems is introduced. The k-closure Ck(G) of a simple graph G of order n is the graph obtained from G by recursively joining pairs of nonadjacent vertices with degree-sum at least k. It is shown that, for many properties P, one can find a suitable value of k (depending on P and n) such that ...

RAINBOW VERTEX CONNECTION NUMBER OF BULL GRAPH, NET GRAPH, TRIANGULAR LADDER GRAPH, AND COMPOSITION GRAPH (P_n [P_1 ])

open access: yesBarekeng
The rainbow connection was first introduced by Chartrand in 2006 and then in 2009 Krivelevich and Yuster first time introduced the rainbow vertex connection. Let graph be a connected graph.

Interval Valued Pentapartitioned Neutrosophic Graphs with an Application to MCDM

open access: yesOperational Research in Engineering Sciences: Theory and Applications, 2022
The concept of interval valued pentapartitioned neutrosophic set is the extension of interval-valued neutrosophic set, quadripartitioned neutrosophic set, interval valued quadripartitioned neutrosophic set and pentapartitioned neutrosophic set.
