New degree-based topological descriptors via m-polynomial of boron α-nanotube
Volume 2, Issue 11 , November 2020, , Pages 1117-1125
Abstract
The study of molecular structure having size less than 100 nm is called nanotechnology. Nano-materials have vast applications in different fields. Boron α-nanotube is very famous ... Read MoreOn 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 MoreEccentricity 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 MoreComputing 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 MoreSome 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 ... Read MoreWeighted 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 ... Read MoreVe-degree and Ev-degree topological analysis of some anticancer drugs
Volume 2, Issue 8 , August 2020, , Pages 834-840
Abstract
Computing topological indices of drug structures provides the chemical information about the underlying topology of the drug’s structures. Novel anticancer drug studies have been ... Read MoreMultiplicative 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 MoreComputing the Narumi-Katayama indices and its modified version of some nanostar dendrimers
Volume 2, Issue 7 , July 2020, , Pages 771-775
Abstract
Dendrimers are the highly branched organic macromolecules with successive layers or generations of branch units surrounding a central core. In mathematical chemistry, a particular attention ... Read MoreOn Van, r and s topological properties of the Sierpinski triangle networks
Volume 2, Issue 7 , July 2020, , Pages 819-826
Abstract
A topological index-a numerical quantity derived from the graph of a chemical network-is used for modelling the mathematical, chemical and physical properties of these networks and ... Read MoreF-leap index of some special classes of bridge and chain graphs
Volume 2, Issue 7 , July 2020, , Pages 827-833
Abstract
The 2-degree of a vertex v in a (molecular) graph G is the number of vertices which are at distance two from v in G. The F-leap index of a molecular graph G is the sum of cubes of the ... Read MoreWeighted entropy of penta chains graph
Volume 2, Issue 6 , June 2020, , Pages 652-662
