Some new inequalities on the normalized signless Laplacian resolvent energy of graphs

Asian-European Journal of Mathematics, 2023
For a connected graph [Formula: see text] of order [Formula: see text] with normalized signless Laplacian eigenvalues [Formula: see text], the normalized signless Laplacian resolvent energy of [Formula: see text] is defined as [Formula: see text]. In this paper, we derive new inequalities on [Formula: see text] as well as relations on [Formula: see ...

On the Energy and Spread of the Adjacency, Laplacian and Signless Laplacian Matrices of Graphs

Match Communications in Mathematical and in Computer Chemistry
In this paper, we explore the connection between the energy and spread of the adjacency, Laplacian, and signless Laplacian matrices for graphs. We then introduce new limitations for the energy and spread of these matrices, based on previous research and our findings.

Signless Laplacian coefficients and incidence energy of unicyclic graphs with the matching number

Linear and Multilinear Algebra, 2014
Let be the characteristic polynomial of the signless Laplacian matrix of a simple graph of order , where and are the degree diagonal and adjacency matrices of , respectively. In this paper, we focus on how the signless Laplacian coefficients of unicyclic graphs change after some graph transformations.

Laplacian and Signless Laplacian Energy of Unitary Cayley Graphs

The Unitary Cayley graph Xn is a graph with vertex set Zn = {0; 1; :::; n - 1} and the edge set {ab/a; b in Zn; gcd(a - b, n) = 1}. In this paper we obtain the eigen values of Laplacian, Signless Laplacian matrix and Laplacian, Signless Laplacian energy of Uni- tary Cayley Graph Xn.
