The behaviour of multi-scale complex systems

Complex systems are often understood to operate across multiple scales (spatial, temporal, or organisational). In this research theme, which began as a group project at the 2018 Santa Fe Institute Complex Systems Summer School, we investigate how to bring these different notions of scale together from an informational perspective. By unifying different types of multi-scale systems under a shared framework, we can identify general patterns in the behavior of complex systems, with particular attention to feedback and adaptation.
