The formalisms of irreversible thermodynamics and information theory are applied to dynamical systems subjected to noise and a periodic forcing, giving rise to multiple steady states and stochastic resonance. It is shown that the passage to multiplicity through a pitchfork bifurcation, the action of noise in general, and the occurrence of stochastic resonance, have clearcut signatures at the level of entropy production and of information entropy. It is suggested that thermodynamic-like quantities provide useful characterizations of the complexity of dynamical systems driven out of equilibrium. © 2000 American Institute of Physics.
