چکیده    Let g be a simple connected graph. the first and second zagreb indices have been introducedas ? ?v?v(g)(v)2 m1(g) degg and m2(g) ? ?uv?e(g)degg(u)degg(v) , respectively,where degg v(degg u) is the degree of vertex v (u) . in this paper, we define a newdistance-based named hyper?zagreb as e uv e(g) .(v))2 hm(g) ? ? ? ? (degg(u) ? degg inthis paper, the hyper?zagreb index of the cartesian product, composition, join anddisjunction of graphs are computed.
