An odd [1, b]-factor in a graph from signless Laplacian spectral radius

RAIRO Oper. Res.
An odd [1,b]-factor of a graph G is a spanning subgraph F of G such that dF(v) is odd and 1 ≤ dF(v) ≤ b for every v ∈ V (G), where b is a positive odd integer. The matrix Q(G) = D(G) + A(G) is called the signless Laplacian matrix of G, where D(G) denotes

Laplacian and signless Laplacian spectrum of commuting graphs of finite groups

2018
Summary: The commuting graph of a finite non-abelian group \(G\) with center \(Z(G)\), denoted by \(\Gamma_G\), is a simple undirected graph whose vertex set is \(G\setminus Z(G)\), and two distinct vertices \(x\) and \(y\) are adjacent if and only if \(xy = yx\).

Common neighborhood (signless) Laplacian spectrum and energy of CCC-graph

Boletim da Sociedade Paranaense de Matemática
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 ...

Signless Laplacian spectrum of a graph

Linear Algebra and its Applications
This article presents a significant contribution to the field of algebraic graph theory with a particular focus on the signless Laplacian spectrum of graphs. The authors successfully establish tight upper bounds for all signless Laplacian eigenvalues of a graph characterized by a prescribed order and minimum degree, notably surpassing previously known ...

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.
