The signless Laplacian spectral radii of modied graphs
Abstract
In this paper, various modifications of a connected graph $G$ are regarded as perturbations of its signless Laplacian matrix. Several results concerning the resulting changes to the signless Laplacian spectral radius of $G$ are obtained by solving intermediate eigenvalue problems of the second type.
