Two Types of Zagreb Indices of Molecular Graphs with Tree Structure
摘要
Abstract
The third Zagreb index and the third version of Zagreb indices of a graph G are M3(G) =∑uv∈ E(G) 丨d(u)-d(v) 丨 and M'1 (G) =∑ u∈ V(G) dG(u)δG(u) respectively.In this paper,we study the two Zagreb indices of molecular graph with tree structure.More precisely,we obtain the bounds for the average and variance of two indices in a randomly chosen molecular graph with tree structure of order n.关键词
