Self‐consistent transfer operators for heterogeneous coupled maps

Source abstract
Abstract We investigate the dynamics of large heterogeneous network dynamical systems composed of nonlocally coupled chaotic maps. We show that the mean‐field limit of such systems is governed by a suitably defined Self‐consistent Transfer Operator (STO) acting on measures, describing the infinite‐size limits of dense graphs as graphons, thereby allowing for a rigorous analysis of the system as the network size tends to infinity. We construct appropriate functional spaces on which the STO has an attracting fixed point, which corresponds to a stable invariant state for the mean‐field limit, and we draw a connection between the regularity properties of the graphons and the regularity of the fixed points. This work combines operator theory and graph limits tools to offer a framework for understanding emergent behavior in complex networks.
