Adaptive dynamical networks

R Berner, T Gross, C Kuehn, J Kurths, S Yanchuk - Physics Reports, 2023 - Elsevier
It is a fundamental challenge to understand how the function of a network is related to its
structural organization. Adaptive dynamical networks represent a broad class of systems that …

[HTML][HTML] Complex dynamics in adaptive phase oscillator networks

B Jüttner, EA Martens - Chaos: An Interdisciplinary Journal of …, 2023 - pubs.aip.org
Networks of coupled dynamical units give rise to collective dynamics such as the

Continuum limits for adaptive network dynamics

MA Gkogkas, C Kuehn, C Xu - arXiv preprint arXiv:2109.05898, 2021 - arxiv.org
Adaptive (or co-evolutionary) network dynamics, ie, when changes of the network/graph
topology are coupled with changes in the node/vertex dynamics, can give rise to rich and …

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 …

MA Gkogkas, B Jüttner, C Kuehn… - … Interdisciplinary Journal of …, 2022 - pubs.aip.org
Models of coupled oscillator networks play an important role in describing collective
synchronization dynamics in biological and technological systems. The Kuramoto model …

Graph limit for interacting particle systems on weighted random graphs

N Ayi, NP Duteil - arXiv preprint arXiv:2307.12801, 2023 - arxiv.org
In this article, we study the large-population limit of interacting particle systems posed on
weighted random graphs. In that aim, we introduce a general framework for the construction …

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 …

Heterogeneous gradient flows in the topology of fibered optimal transport

J Peszek, D Poyato - Calculus of Variations and Partial Differential …, 2023 - Springer
We introduce an optimal transport topology on the space of probability measures over a fiber
bundle, which penalizes the transport cost from one fiber to another. For simplicity, we …

The mean-field Limit of sparse networks of integrate and fire neurons

PE Jabin, D Zhou - arXiv preprint arXiv:2309.04046, 2023 - arxiv.org
We study the mean-field limit of a model of biological neuron networks based on the so-
called stochastic integrate-and-fire (IF) dynamics. Our approach allows to derive a …

Universality of SIS epidemics starting from small initial conditions

D Keliger - Physica A: Statistical Mechanics and its Applications, 2024 - Elsevier
We are investigating deterministic SIS dynamics on large networks starting from only a few
infected individuals. Under mild assumptions we show that any two epidemic curves–on the …
