Abstract
The vertex version of first and second Zagreb indices were introduced by Tavakoli et al. [2] are defined as M ? 1 (G) = P {u,v}?V(G) (dG(u)+dG(v)) and M ? 2 (G) = P {u,v}?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.
