  The mixing properties (or sensitivity to initial conditions) and relaxation
dynamics of the Henon map, together with the connection between these concepts,
have been explored numerically at the edge of chaos. It is found that the
results are consistent with those coming from one-dimensional dissipative maps.
This constitutes the first verification of the scenario in two-dimensional
cases and obviously reinforces the idea of weak mixing and weak chaos.
