Abstract

In this paper, various modications 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.

Keywords

Signless Laplacian spectral radius; modified graph; bound
