Bounds on Vertex Zagreb Indices of Graphs

Global Journal of Science Frontier Research October 11, 2017

The vertex version of first and second Zagreb indices were introduced by Tavakoli et al. [2] are defined as M βˆ— 1 (G) = P {u,v}βŠ†V(G) (dG(u)+dG(v)) and M βˆ— 2 (G) = P {u,v}βŠ†V(G) dG(u)dG(v). In this paper, we obtained the relation between the first and second vertex Zagreb indices of graphs using some well-known results.
