摘要

摘要近年来，树的补类、单圈图、双环图和三环图中谱半径的极值问题得到了广泛的研究。在本文中，我们分别在具有n个顶点的双环图和三环图的所有补中推广了Aα-谱半径的最大序。

The Aα-spectral radius of complements of bicyclic and tricyclic graphs with n vertices

Abstract Recently, the extremal problem of the spectral radius in the class of complements of trees, unicyclic graphs, bicyclic graphs and tricyclic graphs had been studied widely. In this paper, we extend the largest ordering of Aα -spectral radius among all complements of bicyclic and tricyclic graphs with n vertices, respectively.
