On the distance signless Laplacian Estrada index of graphs

Asian-European Journal of Mathematics, 2021
The distance signless Laplacian eigenvalues [Formula: see text] of a connected graph [Formula: see text] are the eigenvalues of the distance signless Laplacian matrix of [Formula: see text], defined as [Formula: see text], where [Formula: see text] is the distance matrix of [Formula: see text] and [Formula: see text] is the diagonal matrix of vertex ...

On the signless Laplacian Estrada index of uniform hypergraphs

International Journal of Quantum Chemistry, 2020
AbstractLet H = (V, E) be a hypergraph and B its incidence matrix. Let Q(H) = BBT be the signless Laplacian matrix of H and λ1(Q), λ2(Q), …, λn(Q) are its eigenvalues. The signless Laplacian Estrada index of H is defined as which is first extended to hypergraph.

Novel Bounds for the Normalized Laplacian Estrada Index and Normalized Laplacian Energy

2017
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 unied approach based on majorization techniques, we provide some novel inequalities depending on additional information on the ...
