Large-population limits of non-exchangeable particle systems

N Ayi, NP Duteil - arXiv preprint arXiv:2401.07748, 2024 - arxiv.org
A particle system is said to be non-exchangeable if two particles cannot be exchanged
without modifying the overall dynamics. Because of this property, the classical mean-field …

Mean-field analysis of multipopulation dynamics with label switching

M Morandotti, F Solombrino - SIAM Journal on Mathematical Analysis, 2020 - SIAM
The mean-field analysis of a multipopulation agent-based model is performed. The model
couples a particle dynamics driven by a nonlocal velocity with a Markov-type jump process …

Mean-field limit of non-exchangeable multi-agent systems over hypergraphs with unbounded rank

N Ayi, NP Duteil, D Poyato - arXiv preprint arXiv:2406.04691, 2024 - arxiv.org
Interacting particle systems are known for their ability to generate large-scale self-organized
structures from simple local interaction rules between each agent and its neighbors. In …

A Stochastic Analysis of Particle Systems with Pairing

V Fromion, P Robert, J Zaherddine - arXiv preprint arXiv:2310.04833, 2023 - arxiv.org
Motivated by a general principle governing regulation mechanisms in biological cells, we
investigate a general interaction scheme between different populations of particles and …

The four levels of fixed-points in mean-field models

S Yasodharan, R Sundaresan - 2021 National Conference on …, 2021 - ieeexplore.ieee.org
The fixed-point analysis refers to the study of fixed-points that arise in the context of complex
systems with many interacting entities. In this expository paper, we describe four levels of …

Fast non-mean-field networks: Uniform in time averaging

J Barré, P Dobson, M Ottobre, E Zatorska - SIAM Journal on Mathematical …, 2021 - SIAM
We study a population of N particles, which evolve according to a diffusion process and
interact through a dynamical network. In turn, the evolution of the network is coupled to the …

A mean field approach for optimization in particles systems and applications

N Gast, B Gaujal - arXiv preprint arXiv:0903.2352, 2009 - arxiv.org
This paper investigates the limit behavior of Markov Decision Processes (MDPs) made of
independent particles evolving in a common environment, when the number of particles …

A large-scale particle system with independent jumps and distributed synchronization

Y Baryshnikov, A Stolyar - arXiv preprint arXiv:2311.17052, 2023 - arxiv.org
We study a system consisting of $ n $ particles, moving forward in jumps on the real line.
Each particle can make both independent jumps, whose sizes have some distribution …

Asymptotic analysis of a particle system with mean-field interaction

A Manita, V Shcherbakov - arXiv preprint math/0408372, 2004 - arxiv.org
We study a system of $ N $ interacting particles on $\bf {Z} $. The stochastic dynamics
consists of two components: a free motion of each particle (independent random walks) and …

Mean-field limits beyond ordinary differential equations

L Bortolussi, N Gast - Formal Methods for the Quantitative Evaluation of …, 2016 - Springer
We study the limiting behaviour of stochastic models of populations of interacting agents, as
the number of agents goes to infinity. Classical mean-field results have established that this …
