On the Laplacian Szeged spectrum of paths
Iranian journal of mathemathical chemistry, 2020We present explicit formulas for the Laplacian Szeged eigenvalues of paths, grids, $C_4$-nanotubes and of Cartesian products of paths with some other simple graphs. A number of open problems is listed.

Laplacian and signless Laplacian spectrum of commuting graphs of finite groups
2018Summary: 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 \(xy = yx\).

On the spectrum of the Laplacian
Mathematische Annalen, 2013Let \((M,g)\) be a complete non-compact Riemannian manifold. Let \(\Delta:=\delta d\) be the Laplacian acting on the space of smooth functions of compact support on \(M\); \(\Delta\) has a unique self-adjoint extension to \(L^2(M)\) which is densely defined and nonnegative.

LAPLACIAN SPECTRUM OF FUZZY CYCLE
Abstract Laplacian spectrum plays a vivacious part in the field of sciences. Multiplicities of integer eigenvalues and spectral effects of various modifications for Laplacian spectrum of simple graphs has been conferred [1]. But, Laplacian spectrum of fuzzy graphs, because of its complexity in calculation, is a barrier in utilizing the concept in ...C. JEBAKIRUBA, A. AMUTHA

The Laplacian Spectrum of a Graph
SIAM Journal on Matrix Analysis and Applications, 1990Let G be a graph. The Laplacian matrix $L(G) = D(G) - A(G)$ is the difference of the diagonal matrix of vertex degrees and the 0-1 adjacency matrix. Various aspects of the spectrum of $L(G)$ are investigated. Particular attention is given to multiplicities of integer eigenvalues and to the effect on the spectrum of various modifications of G.

This chapter gives a self-contained introduction into the Laplacian of compact Riemann surfaces. We prove the spectral theorem using the heat kernel which is given explicitly in Section 7.4 for the hyperbolic plane and in Section 7.5 for the compact quotients. As a tool we use the Abel transform which is introduced in Section 7.3.

Signless Laplacian spectrum of a graph
Linear Algebra and its ApplicationsThis 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 ...
