Abstract

Let G = (V; E), V = fv1; v2; : : :; vng, be a simple graph with n vertices, m edges and a sequence of vertex degrees = d1 d2 dn = , di = d(vi). If vertices vi and vj are adjacent in G, it is denoted as i j, otherwise, we write i j. The rst Zagreb index is vertex-degree-based graph invariant de ned as M1(G) = Pn i=1, whereas the rst Zagreb coindex is de ned as M1(G) = P d 2 i i j (di + dj ). A couple of new upper and lower bounds for M1(G), as well as a new upper bound for M1(G), are obtained.
