On the Fucik spectrum of the p-Laplacian
We prove the existence of a first non-trivial curve in the Fucik spectrum of the p-Laplacian. This yields in particular a variational characterization of the second eigenvalue of the p-Laplacian by a mountain pass procedure.

On the Laplacian and signless Laplacian spectrum of a graph with k pairwise co-neighbor vertices
Consider the Laplacian and signless Laplacian spectrum of a graph G of order n, with k pairwise co-neighbor vertices. We prove that the number of shared neighbors is a Laplacian and a signless Laplacian eigenvalue of G with multiplicity at least k− 1.

On a Class of Laplacian Integral Graphs
A graph whose adjacency (Laplacian) matrix has a spectrum consisting only of integers is called (Laplacian) integral. We observe that a certain class of digraphs is integral as well as Laplacian integral.

Discrete analogue of Fučik spectrum of the Laplacian
The Fučík spectrum of the Laplacian with a Dirichlet boundary condition \((-\Delta u=\alpha u^+-\beta u^-)\) and the discrete analog of the Fučík spectrum for the matrix \(A\) \((M\)-matrices) are considered. This analog has properties similar to those of the continuum.

Adjacency spectra and Laplacian integrality of zero divisor graphs over some rings
Let 𝑅 be a commutative ring and let 𝑍∗ (𝑅) denote the set of non-zero zero divisors of 𝑅. The zero divisor graph 𝛤(𝑅) is defined as the simple graph with vertex set 𝑍∗ (𝑅), where two distinct vertices 𝑥, 𝑦 ∈ 𝑍∗ (𝑅) are adjacent if and only if 𝑥𝑦 = 0.

LAPLACIAN SPECTRUM AND ENERGY OF NON-COMMUTING GRAPHS OF FINITE RINGS [PDF]
We compute spectrum, energy, Laplacian spectrum/ energy and signless Laplacian spectrum/energy of non-commuting graphs of certain finite non-commutative rings. In particular, we consider finite rings $R$ such that $|R| = p^2, p^3, p^4$, $p^5$, $p^2q$ and

Outer Approximation of the Spectrum of a Fractal Laplacian
The Neumann spectrum of a Laplacian on a fractal K in the plane is approximated as a renormalized limit of the Neumann spectra of the standard Laplacian on a sequence of domains which approximate K from the outside.
