Computing F-index, coindex and Zagreb polynomials of the kth generalized transformation graphs [PDF]

open access: yesHeliyon, 2020
In chemical graph theory, forgotten topological index or F-index plays a crucial role to collect information about the properties of chemical compounds. The kth generalized transformation graphs of a molecular graph preserve the entire information on the

Computing Zagreb Indices and Zagreb Polynomials for Symmetrical Nanotubes [PDF]

open access: yesSymmetry, 2018
Topological indices are numbers related to sub-atomic graphs to allow quantitative structure-movement/property/danger connections. These topological indices correspond to some specific physico-concoction properties such as breaking point, security, strain vitality of chemical compounds.

Some Novel Results Involving Prototypical Computation of Zagreb Polynomials and Indices for SiO4 Embedded in a Chain of Silicates [PDF]

open access: yesMolecules, 2022
A topological index as a graph parameter was obtained mathematically from the graph’s topological structure. These indices are useful for measuring the various chemical characteristics of chemical compounds in the chemical graph theory.

Zagreb Polynomials and redefined Zagreb indices of Dendrimers and Polyomino Chains [PDF]

open access: yesOpen Chemistry, 2019
Dendrimers have an incredibly strong potential because their structure allows multivalent frameworks, i.e. one dendrimer molecule has many possible destinations to couple to a functioning species.

Computation of Zagreb Indices and Zagreb Polynomials of Sierpinski Graphs

open access: yesHacettepe Journal of Mathematics and Statistics, 2020
The Sierpinski fractal or Sierpinski gasket and generalized Sierpinski graphs are objects of great interest in dynamical systems and probability. In this paper, we consider the Sierpinski gasket graph $S_{n}$, the generalized Sierpinski graphs $S(n,C_{3})$ and $S(n,C_{4})$.
