Unicycle graphs with maximum generalized topological indices

Let G be an unicycle graph and dv the degree of the vertex v. In this paper, we investigate the following topological indices for an unicycle graph , , where m ≥ 2 is an integer. All unicycle graphs with the largest values of the three topological indices are characterized.
