1. On The Degree-Based Topological Descriptors of Star of David and Hexagonal Cage Networks
Articles in Press, Accepted Manuscript, Available Online from 24 October 2020
Abstract
Topological indices are a graph 's numerical parameters which characterise its molecular topology. In theoretical chemistry, the numerical parameters which are used to characterized the molecular topology of graphs are called topological indices. Several physical and chemical properties like boiling ... Read More
2. 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 recent eccentricity-based topological index called Leap eccentric connectivity index (LECI), which is defined as the sum ... Read More
3. Weighted entropy of Zig-Zag chain
Volume 2, Issue 10 , October 2020, , Pages 1082-1087
Abstract
The entropy of a graph is a functional depending both on the graph itself and on a probability distribution on its vertex set. This graph functional originated from the problem of source coding in information theory and was introduced by J. Krner in 1973. Although the notion of graph entropy has its ... Read More
4. Some topological descriptors and algebraic polynomials of Pm+FPm
Volume 2, Issue 10 , October 2020, , Pages 1072-1081
Abstract
A topological index of G is a quantity related to G that characterizes its topology. Properties of the chemical compounds and topological invariants are related to each other. In this paper, we derive the algebraic polynomials including first and second Zagreb polynomials, and forgotten polynomial for ... Read More
5. 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, then it is termed as discrepancy. This paper mainly deals with metric dimension and partition dimension of tessellation ... Read More

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 hierarchical product of graphs was computed. Further, we obtained some explicit expressions of eccentricity version ...
