REDUCED SECOND ZAGREB INDEX OF BICYCLIC GRAPHS WITH PENDENT VERTICES [PDF]

open access: yes, 2016
Reduced second Zagreb index has been defined recently. In this paper we characterized extremal bicyclic graphs with pendent vertices with respect to this novel ...

On hyper–Zagreb index and coindex [PDF]

open access: yes, 2017
Let G be a graph with vertex set V and edges set E. By d(v) is denoted the degree of its vertex v. Two much studied degree–based graph invariants are the first and second Zagreb indices.

Sharp Bounds of the Hyper-Zagreb Index on Acyclic, Unicylic, and Bicyclic Graphs [PDF]

open access: yes, 2017
The hyper-Zagreb index is an important branch in the Zagreb indices family, which is defined as ∑uv∈E(G)‍(d(u)+d(v))2, where d(v) is the degree of the vertex v in a graph G=(V(G),E(G)). In this paper, the monotonicity of the hyper-Zagreb index under some

The Third Leap Zagreb Index for Trees

open access: yes, 2019
The third leap Zagreb index is the sum of the products of vertex degrees and second degrees. In this paper, a lower bound on the third leap Zagreb index is established, and the extremal trees achieving this bound are ...
