Abstract

Two Laplacian energies and the relations between them

Highlights

  • Let M be a real symmetric square matrix of order n

  • The paper contributes to the Laplacian spectral theory and the theory of graph energies

  • As a rough approximation, Laplacian energy (LE) is proportional to the tem (Z-4m2/n)1/2

Summary

Introduction

Let M be a real symmetric square matrix of order n. Conclusion: The paper contributes to the Laplacian spectral theory and the theory of graph energies. The energy of M is defined as (Nikiforov, 2007), (Gutman & Furtula, 2019): We are concerned with the Laplacian energy.
