设G是简单连通图。第一个和第二个萨格勒布指数分别被引入为v V(G)(v)2 M1(G)degG和M2(G)uv E(G)degG(u)degG(v),其中degG v(degG u)是顶点v(u)的度。在本文中,我们定义了一个新的基于距离的Hyper Zagreb为e uv E(G)。(v))2 HM(G)<$G(u)<$degG本文计算了图的笛卡尔积、合成、并和析取的超Zagreb指数。
Let G be a simple connected graph. The first and second Zagreb indices have been introduced as  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 new distance-based named HyperZagreb as e uv E(G) . (v))2 HM(G)     (degG(u)  degG In this paper, the HyperZagreb index of the Cartesian product, composition, join and disjunction of graphs are computed.
