The Chirikov criterion, formulated by Boris Chirikov in the early 1970s, is a condition used to identify the onset of stochasticity in classical dynamical systems, particularly in the context of Hamiltonian mechanics. It provides a way to determine when a system that is expected to be integrable (meaning it has well-defined behavior) becomes chaotic due to the presence of small perturbations.
