Theoretical analysis identifies graphs achieving extremal signless Laplacian and Aα-spectral radii under fixed connectivity, highlighting structural bounds in spectral graph theory.
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.
