On the zagreb indices of the line graphs of polyphenylene dendrimers

Abstract

In predicting of their bioactivity and physicochemical properties of a chemical graph extremely important correlated with mathematical invariants in the topological indices. These topological indices are well-known in mathematical chemistry, drugs delivery, biology, gene therapy, nanotechnology and in other areas of applied sciences. In this paper, we study two families of Polyphenylene dendrimers, namely D1[n] and D2[n]. We also compute their topological indices, Zagreb indices and Zagreb coindices based on the concept of the line graphs. Furthermore, we analyze the results of these indices for graphs D1[n] and D2[n].
