摘要
Hysteresis in randomly perturbed fast dynamical systems is studied. By using the theory of large deviations, it is demonstrated that noise may induce hysteresis in fast systems that do not exhibit it otherwise, or it may appreciably alter the characteristics of hysteresis present in the absence of noise. The case of dynamical systems with many attractors is especially studied and the mathematical machinery for identifying the attractors through which such systems evolve is presented.
