Differential inclusions in Wasserstein spaces: the Cauchy-Lipschitz framework

B Bonnet, H Frankowska - Journal of Differential Equations, 2021 - Elsevier
In this article, we propose a general framework for the study of differential inclusions in the
Wasserstein space of probability measures. Based on earlier geometric insights on the …

Mean-field and graph limits for collective dynamics models with time-varying weights

N Ayi, NP Duteil - Journal of Differential Equations, 2021 - Elsevier
In this paper, we study a model for opinion dynamics where the influence weights of agents
evolve in time via an equation which is coupled with the opinions' evolution. We explore the …

[HTML][HTML] Graph-to-local limit for the nonlocal interaction equation

A Esposito, G Heinze, A Schlichting - Journal de Mathématiques Pures et …, 2025 - Elsevier
We study a class of nonlocal partial differential equations presenting a tensor-mobility, in
space, obtained asymptotically from nonlocal dynamics on localising infinite graphs. Our …

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 …

Consensus formation in first-order graphon models with time-varying topologies

B Bonnet, NP Duteil, M Sigalotti - Mathematical Models and Methods …, 2022 - World Scientific
In this paper, we investigate the asymptotic formation of consensus for several classes of
time-dependent cooperative graphon dynamics. After motivating the use of this type of …

Consensus based optimization with memory effects: random selection and applications

G Borghi, S Grassi, L Pareschi - Chaos, Solitons & Fractals, 2023 - Elsevier
In this work we extend the class of Consensus-Based Optimization (CBO) metaheuristic
methods by considering memory effects and a random selection strategy. The proposed …

[HTML][HTML] Mean field limit for one dimensional opinion dynamics with Coulomb interaction and time dependent weights

I Ben-Porat, JA Carrillo, ST Galtung - Nonlinear Analysis, 2024 - Elsevier
The mean field limit with time dependent weights for a 1D singular case, given by the
attractive Coulomb interactions, is considered. This extends recent results (Ayi and Duteil …

Inference of interaction kernels in mean-field models of opinion dynamics

W Chu, Q Li, MA Porter - SIAM Journal on Applied Mathematics, 2024 - SIAM
In models of opinion dynamics, many parameters—either in the form of constants or in the
form of functions—play a critical role in describing, calibrating, and forecasting how opinions …

Mean-field limit of collective dynamics with time-varying weights

NP Duteil - arxiv preprint arxiv:2103.06527, 2021 - arxiv.org
In this paper, we derive the mean-field limit of a collective dynamics model with time-varying
weights, for weight dynamics that preserve the total mass of the system as well as …

Cherry picking: Consumer choices in swarm dynamics, considering price and quality of goods

D Knopoff, V Secchini, P Terna - Symmetry, 2020 - mdpi.com
This paper proposes a further development of the mathematical theory of swarms to
behavioral dynamics of social and economic systems, with an application to the modeling of …
