Fractal and statistical characteristics of recurrence times
(68K, LATeX 2e)

ABSTRACT.  In this paper we introduce and discuss two proprieties related to recurrences
in dynamical systems. The first gives the asymptotic law for the return 
time in a neighborhood, while the second gives a topological index of fractal
type to characterize the system or some regions of the system.
