Bounds for Kirchhoff index and Laplacian-energy-like invariant of some derived graphs of a regular graph

Discrete Mathematics, Algorithms and Applications, 2020
The Kirchhoff index and Laplacian-energy-like invariant of a connected graph [Formula: see text], denoted by [Formula: see text] and [Formula: see text], are given by the number of vertex times the sum of the reciprocals of all nonzero Laplacian eigenvalues of [Formula: see text] and the sum of the square roots of all Laplacian eigenvalues of [Formula:

A note on the bounds of Laplacian-energy-like-invariant

2018
Summary: The Laplacian-energy-like of a simple connected graph \(G\) is defined as \(\mathrm{LEL}:=\mathrm{LEL}(G)=\sum_{(i=1)}^n\sqrt{\mu_i}\), where \(\mu_1(G)\geq \mu_2 (G)\geq\dots\geq\mu_n(G)=0\) are the Laplacian eigenvalues of the graph \(G\). In this paper, some upper and lower bounds for LEL as well as some lower bounds for the spectral radius
