Relations between ordinary energy and energy of a self-loop graph

open access: yesHeliyon
Let G be a graph on n vertices with vertex set V(G) and let S⊆V(G) with |S|=α. Denote by GS, the graph obtained from G by adding a self-loop at each of the vertices in S.

Design of Control Structure for Integrated Process Networks Based on Graph-theoretic Analysis

open access: yesChemical Engineering Transactions, 2017
A novel graph representation is developed to address the control structure selection of the process networks featuring multiple scale material and energy dynamics, which is a combination of the process flow graph and energy flow graph so that both the ...

On energy, Laplacian energy and p-fold graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2015
Summary: For a graph \(G\) having adjacency spectrum \((A\)-spectrum) \( \lambda_n\leq\lambda_{n-1}\leq\cdots\leq\lambda_1\) and Laplacian spectrum \((L\)-spectrum) \(0=\mu_n\leq\mu_{n-1}\leq\cdots\leq\mu_1\), the energy is defined as \(E(G)=\sum_{i=1}^n|\lambda_i|\) and the Laplacian energy is defined as \(LE(G)=\sum_{i=1}^n|\mu_i-\frac{2m}{n}|\).

Some improved bounds on two energy-like invariants of some derived graphs

open access: yesOpen Mathematics, 2019
Given a simple graph G, its Laplacian-energy-like invariant LEL(G) and incidence energy IE(G) are the sum of square root of its all Laplacian eigenvalues and signless Laplacian eigenvalues, respectively. This paper obtains some improved bounds on LEL and

Energy-weighted message passing: an infra-red and collinear safe graph neural network algorithm

open access: yes, 2022
Hadronic signals of new-physics origin at the Large Hadron Collider can remain hidden within the copiously produced hadronic jets. Unveiling such signatures require highly performant deep-learning algorithms. We construct a class of Graph Neural Networks

The Sum-Eccentricity Energy of A Graph [PDF]

open access: yes, 2017
In this paper, we introduce the concept of the sum-eccentricity matrix of a graph and obtain some coefficients of the characteristic polynomial of the sum-eccentricity matrix of . We also introduce the sum-eccentricity energy of a graph .
