The signless Laplacian Estrada index of tricyclic graphs
The signless Laplacian Estrada index of a graph $G$ is defined as $SLEE(G)=\sum^{n}_{i=1}e^{q_i}$ where $q_1, q_2, \ldots, q_n$ are the eigenvalues of the signless Laplacian matrix of $G$. In this paper, we show that there are exactly two tricyclic graphs with the maximal signless Laplacian Estrada index.

On sum of powers of Laplacian eigenvalues and Laplacian Estrada index of graphs
Let $G$ be a simple graph and $α$ a real number. The quantity $s_α(G)$ defined as the sum of the $α$-th power of the non-zero Laplacian eigenvalues of $G$ generalizes several concepts in the literature. The Laplacian Estrada index is a newly introduced graph invariant based on Laplacian eigenvalues.

Maximum signless Laplacian Estrada index of tetracyclic graphs
In this study, we aim to determine the unique tetracyclic graph that maximizes the signless Laplacian Estrada index (SLEE) among all tetracyclic graphs. The SLEE of a graph ? is defined as the sum of the exponentials of its eigenvalues, expressed as follows: SLEE(?)=?n,i=1 esi, where s1, s2,...,sn are the eigenvalues of the signless Laplacian matrix ...

Novel Bounds for the Normalized Laplacian Estrada and Normalized Energy Index of Graphs
For a simple and connected graph, several lower and upper bounds of graph invariants expressed in terms of the eigenvalues of the normalized Laplacian matrix have been proposed in literature. In this paper, through a unified approach based on majorization techniques, we provide some novel inequalities depending on additional information on the ...
