From microscopic to macroscopic scale dynamics: mean field, hydrodynamic and graph limits

T Paul, E Trélat - 2024 - hal.science
Considering deterministic finite particle systems, we elaborate on various ways to pass to
the limit as the number of agents tends to infinity, either by mean field limit, deriving the …

From microscopic to macroscopic scale equations: mean field, hydrodynamic and graph limits

T Paul, E Trélat - arXiv preprint arXiv:2209.08832, 2022 - arxiv.org
We elaborate on various ways to pass to the limit a given family of finite-dimensional particle
systems, either by mean field limit, deriving the Vlasov equation, or by hydrodynamic or …

[PDF][PDF] Dynamics of large particle systems

M Iacobelli - 2015 - mat.uniroma1.it
This thesis is devoted to the mathematical study of problems involving the general question
of the interaction between continuous and discrete objects. More precisely, one wants to …

Mean field limit and propagation of chaos for Vlasov systems with bounded forces

PE Jabin, Z Wang - Journal of Functional Analysis, 2016 - Elsevier
We consider large systems of particles interacting through rough but bounded interaction
kernels. We are able to control the relative entropy between the N-particle distribution and …

Long time behavior of particle systems in the mean field limit

E Caglioti, F Rousset - 2007 - projecteuclid.org
We present a review of some recent results concerning the long time behavior of particle
systems in the mean field limit. In particular we will consider the Vlasov limit for a system of …

Network dynamics on graphops

C Kuehn - New Journal of Physics, 2020 - iopscience.iop.org
In this article we report on a novel way to incorporate complex network structure into the
analysis of interacting particle systems. More precisely, it is well-known that in well …

Mean field limit for the one dimensional Vlasov-Poisson equation

M Hauray - Séminaire Laurent Schwartz—EDP et applications, 2012 - numdam.org
We consider systems of N particles in dimension one, driven by pair Coulombian or
gravitational interactions. When the number of particles goes to infinity in the so called mean …

A note on Fokker–Planck equations and graphons

F Coppini - Journal of Statistical Physics, 2022 - Springer
Fokker–Planck equations represent a suitable description of the finite-time behavior for a
large class of particle systems as the size of the population tends to infinity. Recently, the …

The rigorous derivation of Vlasov equations with local alignments from moderately interacting particle systems

J Wang, M Zhuang, H Huang - arXiv preprint arXiv:2407.04387, 2024 - arxiv.org
In this paper, we present a rigorous derivation of the mean-field limit for a moderately
interacting particle system in $\R^ d $$(d\geq 2) $. For stochastic initial data, we …

Cauchy theory for general Vicsek models in collective dynamics and mean-field limit approximations

M Briant, A Diez, S Merino-Aceituno - arXiv preprint arXiv:2004.00883, 2020 - arxiv.org
In this paper we provide a local Cauchy theory both on the torus and in the whole space for
general Vicsek dynamics at the kinetic level. We consider rather general interaction kernels …
