The Hosoya polynomial of a graph, H(G, z), has the property that its first derivative, evaluated at z = 1, equals the Wiener index, i.e ., W(G) = H'(G, 1). In this paper, an equation is presented that gives the hyper-Wiener index, WW(G), in terms of the first and second derivatives of H(G,z). ## A
Graph theory was successfully applied in developing a relationship between chemical structure and biological activity. The relationship of two graph invariants αthe eccentric connectiΒ¨ity index and the Wiener's index was investigated with regard to anti-inflammatory activity, for a data set consisti
