Fundamental Limits of Stability Inference in High-Dimensional Complex Systems

Michela Costa, Kentaro Hoshisashi, Flaviano Morone +2

Many complex systems, including ecosystems, neural circuits, and financial markets, are inferred to operate close to a threshold of instability, at which a small perturbation can p…
