| Abstract: | A simple connected graph in which the number of edges equals to the number of vertices plus two is called a tricyclic graph. Let Rn（k） be the set of all tricyclic graphs with n vertices and k pendent vertices. According to the classification on tricyclic graphs in the Reference, in this paper, the tricyclic graphs with maximum spectral radii among those classes of tricyclic graphs are determined respectively. |

| Keywords: | pendant vertex tricyclic graph spectral radius maximum eigenvector |
