The Zaslavskii map arose from consideration of the problem of a dissipative kicked rotor; it exhibits chaotic behavior. It is claimed to be the simplest problem producing a strange attractor. The approach described involves the so-called action-angle variables of Hamiltonian dynamics (in which frequencies can be obtained without actually solving the equations of motion).
