Zagreb Indices of Trees, Unicyclic and Bicyclic Graphs With Given (Total) Domination
Let G = (V, E) be a (molecular) graph. For a family of graphs G, the first Zagreb index M1 and the second Zagreb index M2 have already studied. In particular, it has been presented, the first Zagreb index M1 and the second Zagreb index M2 of trees T in ...

The Zagreb Index of Several Random Models
In this article, we investigate the Zagreb index, a kind of graph-based topological index, of several random networks, including a class of networks extended from random recursive trees, plain-oriented recursive trees, and random caterpillars growing in a preferential attachment manner.

A note on multiplicative sum Zagreb index [PDF]
For a nontrivial (molecular) graph G, its multiplicative sum Zagreb index, denoted by π * 1 (G), is defined as the product of the sum is the degree of vertex u.
