Eigenvalue bounds for the signless -Laplacian

arXiv:1610.01357

Abstract

We consider the signless -Laplacian of a graph, a generalisation of the usual signless Laplacian (the case ). We show a Perron-Frobenius property and basic inequalites for the largest eigenvalue and provide upper and lower bounds for the smallest eigenvalue in terms of a parameter related to the bipartiteness. The latter result generalises bounds by Desai and Rao and, interestingly, in the limit upper and lower bounds coincide.
