The geometric arithmetic (GA) index of certain trees and bicyclic graphs
Volume 3, Issue 9 , September 2021, , Pages 635-643
Abstract
The geometric arithmetic index is one of the recently most investigated degree-based molecular structure descriptors that have applications in chemistry. For a graph , the index ... Read More
On leap eccentric connectivity index of thorny graphs
Volume 2, Issue 10 , October 2020, , Pages 1033-1039
Abstract
The 2-degree of a vertex v of a simple graph G is the number of vertices which are at distance two from v in G and is denoted by d2(v). In this article, we compute exact values of a ... Read More
Eccentricity version F-index of some graph operations
Volume 2, Issue 10 , October 2020, , Pages 1059-1063
Abstract
The eccentricity version F-index of a graph G is defined as the summation of cube of all the vertex eccentricities of G. In this report, the eccentricity version of F-index of the generalized ... Read More
Computing metric and partition dimension of tessellation of plane by boron nanosheets
Volume 2, Issue 10 , October 2020, , Pages 1064-1071
Abstract
Metric dimension dim(G) and portion dimension pd(G) are usually related as pd(G)≤dim(G)+1. However, if the partition dimension is significantly smaller than the metric dimension, ... Read More
Multiplicative leap Zagreb indices of T-thorny graphs
Volume 2, Issue 8 , August 2020, , Pages 841-846
Abstract
Let G=(V, E) is a molecular graph in which the vertex set V represents atoms and the edge set E represents the bonds between the atoms, corresponding to a chemical compound. In this ... Read More
