Asymptotic behavior of Laplacian-energy-like invariant of the 3.6.24 lattice with various boundary conditions. [PDF]
Let G be a connected graph of order n with Laplacian eigenvalues [Formula: see text]. The Laplacian-energy-like invariant of G, is defined as [Formula: see text]. In this paper, we investigate the asymptotic behavior of the 3.6.24 lattice in terms of Laplacian-energy-like invariant as m, n approach infinity.

On two energy-like invariants of line graphs and related graph operations [PDF]
For a simple graph G of order n, let μ 1 ≥ μ 2 ≥ ⋯ ≥ μ n = 0 $\mu_{1}\geq\mu_{2}\geq\cdots\geq\mu_{n}=0$ be its Laplacian eigenvalues, and let q 1 ≥ q 2 ≥ ⋯ ≥ q n ≥ 0 $q_{1}\geq q_{2}\geq\cdots\geq q_{n}\geq0$ be its signless Laplacian eigenvalues.

Some observations on the Laplacian-energy-like invariant of trees [PDF]
Summary: Let \(G\) be a graph of order \(n\). Denote by \(A\) the adjacency matrix of \(G\) and by \(D=\mathrm{diag}(d_1, \dots, d_n)\) the diagonal matrix of vertex degrees of \(G\). The Laplacian matrix of \(G\) is defined as \(L=D - A\). Let \(\mu_1, \mu_2,\cdots, \mu_{n-1}, \mu_n\) be eigenvalues of \(L\) satisfying \(\mu_1\geq \mu_2\geq \dots \geq

On Laplacian resolvent energy of graphs [PDF]
Let $G$ be a simple connected graph of order $n$ and size $m$. The matrix $L(G)=D(G)-A(G)$ is the Laplacian matrix of $G$, where $D(G)$ and $A(G)$ are the degree diagonal matrix and the adjacency matrix, respectively. For the graph $G$, let $d_{1}\geq d_{

(Generalized) Incidence and Laplacian-Like Energies
In this study, for graph Γ with r connected components (also for connected nonbipartite and connected bipartite graphs) and a real number ε≠0,1, we found generalized and improved bounds for the sum of ε-th powers of Laplacian and signless Laplacian ...

The Laplacian-Energy-Like Invariants of Three Types of Lattices [PDF]
This paper mainly studies the Laplacian-energy-like invariants of the modified hexagonal lattice, modified Union Jack lattice, and honeycomb lattice. By utilizing the tensor product of matrices and the diagonalization of block circulant matrices, we derive closed-form formulas expressing the Laplacian-energy-like invariants of these lattices.

NORMALIZED LAPLACIAN ENERGY AND NORMALIZED LAPLACIAN-ENERGY-LIKE INVARIANT OF SOME DERIVED GRAPHS
Summary: For a connected graph \(G\), the smallest normalized Laplacian eigenvalue is 0 while all others are positive and the largest cannot exceed the value 2. The sum of absolute deviations of the eigenvalues from 1 is called the normalized Laplacian energy, denoted by \(\mathbb{LE}(G)\).
