| Abstract: | The spectral moments are the important algebraic invariants of graphs. In this paper, on the basis of definitions of tricyclic graphs, base and the sequence of spectral moments, respectively, we study tricyclic graphs with given bases on the lexicographical order of the spectral moments sequence, and find the last and the first graphs. The results is very helpful for studying all tricyclic graphs ordering by spectral moments. |
