A Graph-Based Power Flow Method for Balanced Distribution Systems
Energies, 2018 A power flow method based on graph theory is presented for three-phase balanced distribution systems. The graph theory is used to describe the power network and facilitate the derivation of the relationship between bus Currents and the bus Voltage Bias ...

Optimization Model of Closed Loop Supply Chain Based on System Dynamics and Graph Theory
International Journal of u- and e- Service, Science and Technology, 2016 In order to assist in the reverse recovery decision of emergency logistics in sudden natural disasters, this paper conducts the system modeling on the reverse recovery of reusable materials in several disaster areas from the perspective of system dynamics under the principle of rescue satisfaction preference.

Network dismantling on factor graphs: break long loops and spare local structures
New Journal of Physics, 2021 A new solution framework for the task of network dismantling is recently developed, based on a two-scale bipartite factor-graph representation of the original graph where local structures are abstracted as factor nodes.

Color/kinematics duality for general abelian orbifolds of N=4 super Yang-Mills theory [PDF]
, 2014 To explore color/kinematics duality for general representations of the gauge group we formulate the duality for general abelian orbifolds of the SU(N), N=4 super Yang-Mills theory in four dimensions, which have fields in the bi-fundamental representation,

Making multigraphs simple by a sequence of double edge swaps
, 2021 We show that any loopy multigraph with a graphical degree sequence can be transformed into a simple graph by a finite sequence of double edge swaps with each swap involving at least one loop or multiple edge.

Perfecting one-loop BCJ numerators in SYM and supergravity
Journal of High Energy Physics, 2023 We take a major step towards computing D-dimensional one-loop amplitudes in general gauge theories, compatible with the principles of unitarity and the color-kinematics duality.

On One-Loop Gap Equations for the Magnetic Mass in d=3 Gauge Theory [PDF]
, 1997 Recently several workers have attempted determinations of the so-called magnetic mass of d=3 non-Abelian gauge theories through a one-loop gap equation, using a free massive propagator as input.

Feynman graph generation and calculations in the Hopf algebra of Feynman graphs
, 2014 Two programs for the computation of perturbative expansions of quantum field theory amplitudes are provided. feyngen can be used to generate Feynman graphs for Yang-Mills, QED and $\varphi^k$ theories.
