Abstract
We study such nonlinear mappingsx n +1=F(x n ;b cr) of an intervalI into itself for which the Feigenbaum scaling laws hold (i.e., for which bcr is an accumulation point of bifurcation points). Letx 0 be a random variable with some absolutely continuous distribution inI. We show in particular that (i) the geometric average distance ofx n from the nearest point of the attractor decreases liken −1.93387; (ii) the geometric average of ¦∂x n /∂x 0¦ increases liken 0.60; (iii) the geometric mean distance ¦x n −y n ¦ between the iterates of two close-by pointsx 0,y 0 asymptotically tends towards a value ∼¦x 0−y 0¦0.77. These-and other-properties are also borne out from a simple probabilistic model which depicts the evolution as a random walklike process.
