| Abstract: | The Wiener index of a connected graph G is defined as the sum of distances between pairs of vertices. The terminal Wiener index of a connected graph G is defined as the sum of distances between pairs of pendant vertices. In this paper the Wiener and terminal Wiener indices of a modified generalized Bethe tree are obtained,the Wiener and terminal Wiener indices of the coalescence of two modified generalized Bethe trees at rooted vertices are also obtained. Meanwhile two topological indices for modified dendrimer trees are computed. |
