Zagreb Polynomials and redefined Zagreb indices of nanostar dendrimers

Abstract

Dendrimers are profoundly extended natural macromolecules with successive layers of branch units encompassing a central core. Topological indicess are numbers related with graph of a compound to allow quantitative structureactivity/property/lethality connections. These topological indices relate certain physico-chemical properties like stability, boiling point, strain energy and so forth of a compound. In this report, there have been computed redefined first, second and third Zagreb indices of Nanostar dendrimers. The authors also analyzed some Zagreb polynomials of understudy dendrimers.

Certain Energies of Graphs for Dutch Windmill and Double‐Wheel Graphs

“…Now, the sum of the absolute values of the roots of this characteristic equation determines the Harary energy of the graph under consideration. For other useful results, we refer to the readers [14][15][16][17].…”

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

“…For different recent study of -index and its co-index, we refer to [8,16,17]. In order to know more about Zagreb polynomials and its co-polynomials for various transformation graphs see [15,18,19]. The following Propositions are instrumental in proving for the present considerations.…”

Some New Bounds of Weighted Graph Entropies with GA and Gaurava Indices Edge Weights

“…e predictive power of the GA index is compared with others such as the famous Randić index [17]. Due to this reason, different versions of the GA index are now investigated and introduced in the literature [18][19][20]. e other famous indices are given in [21].…”
