Year: 2026
Type: article
Abstract: In this paper, we characterize the graphs with a second maximum signless Laplacian spectral radius among all graphs with a fixed order and fixed vertex or edge connectivity. We also discuss the maximum and second maximum Aα-spectral radius of graphs subject to fixed connectivity.
