Mean-field limits for stochastic particle systems on dense graphs
Angeliki Koutsimpela, Elena Magnanini
We study stochastic interacting particle systems whose interaction structure is described by dense weighted directed graphs converging to a graphon. In the thermodynamic limit, we…

Mean-field limits in interacting particle systems with symmetric superlinear rates
Angeliki Koutsimpela
We derive the exchange-driven growth (EDG) equations as the mean-field limit of interacting particle systems on the complete graph. Extending previous work, we consider symmetric e…

Tagged particles and size-biased dynamics in mean-field interacting particle systems
Angeliki Koutsimpela, Stefan Grosskinsky
We establish a connection between tagged particles and size-biased empirical processes in interacting particle systems, in analogy to classical results on the propagation of chaos.…
