H+-EIGENVALUES OF LAPLACIAN AND SIGNLESS LAPLACIAN TENSORS
, 2014 We propose a simple and natural definition for the Laplacian and the signless Lapla-cian tensors of a uniform hypergraph. We study their H+-eigenvalues, i.e., H-eigenvalues with non-negative H-eigenvectors, and H++-eigenvalues, i.e., H-eigenvalues with ...

On the eigenvalues of the distance signless Laplacian matrix of graphs
Let G be a connected graph and let DQ(G) be the distance signless Laplacian matrix of G with eigenvalues ρ1≥ ρ2≥…≥ ρn. The spread of the matrix DQ}(G) is defined as s(DQ(G)) := maxi,j| ρi-ρj| = ρ1- ρn.

Common neighborhood (signless) Laplacian spectrum and energy of CCC-graph
In this paper, we consider commuting conjugacy class graph (abbreviated as CCC-graph) of a finite group $G$ which is a graph with vertex set $\{x^G : x \in G \setminus Z(G)\}$ (where $x^G$ denotes the conjugacy class containing $x$) and two distinct ...
