Mean-Field Limits for Stochastic Interacting Particles on Digraph Measures

C Kuehn, C Pulido - arXiv preprint arXiv:2403.20325, 2024 - arxiv.org
Many natural phenomena are effectively described by interacting particle systems, which
can be modeled using either deterministic or stochastic differential equations (SDEs). In this …

Vlasov equations on digraph measures

C Kuehn, C Xu - Journal of Differential Equations, 2022 - Elsevier
Many science phenomena are described as interacting particle systems (IPS). The mean
field limit (MFL) of large all-to-all coupled deterministic IPS is given by the solution of a PDE …

Vlasov equations on directed hypergraph measures

C Kuehn, C Xu - arXiv preprint arXiv:2207.03806, 2022 - arxiv.org
In this paper we propose a framework to investigate the mean field limit (MFL) of interacting
particle systems on directed hypergraphs. We provide a non-trivial measure-theoretic …

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 limits of co-evolutionary heterogeneous networks

MA Gkogkas, C Kuehn, C Xu - arXiv preprint arXiv:2202.01742, 2022 - arxiv.org
Many science phenomena are modelled as interacting particle systems (IPS) coupled on
static networks. In reality, network connections are far more dynamic. Connections among …

Global stability for McKean-Vlasov equations on large networks

C Kuehn, T Wöhrer - arXiv preprint arXiv:2312.15335, 2023 - arxiv.org
We investigate the mean-field dynamics of stochastic McKean differential equations with
heterogeneous particle interactions described by large network structures. To express a …

Weakly interacting oscillators on dense random graphs

G Bet, F Coppini, FR Nardi - Journal of Applied Probability, 2024 - cambridge.org
We consider a class of weakly interacting particle systems of mean-field type. The
interactions between the particles are encoded in a graph sequence, ie two particles are …

Accuracy of the Graphon Mean Field Approximation for Interacting Particle Systems

S Allmeier, N Gast - arXiv preprint arXiv:2405.08623, 2024 - arxiv.org
We consider a system of $ N $ particles whose interactions are characterized by a
(weighted) graph $ G^ N $. Each particle is a node of the graph with an internal state. The …

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 …

Graphop mean-field limits for Kuramoto-type models

MA Gkogkas, C Kuehn - SIAM Journal on Applied Dynamical Systems, 2022 - SIAM
Originally arising in the context of interacting particle systems in statistical physics,
dynamical systems and differential equations on networks/graphs have permeated into a …
