| Abstract: | Let G be an unicycle graph and d~ be the degree of the vertex v. Investigates the following topologicall indices for an unicycle graph G： otto G： m（G）=∑v∈v（G）dv^m,-m（G）=∑v∈v（G）dv^-m , -1/m（G）=∑v∈v（G）dv^-1/m, here m is a positive interger not less than 2, describes the unicycle graph with the smallest value of the three topological indices. |
