Scaling properties and functional properties of the e-critic in the standard map.

Abstract: We study the scaling low of the function e-critic when the frequency approaches a rational value. We give also a numerical proof of the fact that log e-critic is a bmo(p4) function. These results ae a joint work with J. Laskar & S. Marmi.
