Abstract
We consider the dynamical system described by the area-preserving standard mapping. It is known for this system that , the normalized number of recurrences staying in some given domain of the phase space at time (so-called “survival probability”) has the power-law asymptotics, . We present new semiphenomenological arguments which enable us to map the dynamical system near the chaos border onto the effective “ultrametric diffusion” on the boundary of a treelike space with hierarchically organized transition rates. In the framework of our approach we have estimated the exponent as , where is the critical rotation number.
