Fisher information and nonlinear dynamics

The past decade has witnessed an impressive growth in the scope and variety of physical applications of Fisherʹs information measure (FIM). As a consequence, FIM is widely regarded today as providing one with a unifying principle for physics. In the present paper, we investigate its usefulness in connection with the description of important aspects of the behavior of dynamical systems, and find that the unification referred to above can be extended to the field of these systems.
