A NON-ERGODIC PHENOMENON FOR SOME RANDOM DYNAMICAL SYSTEM

Andrzej Komisarski

Abstract: In [2] Jajte formulated the following question:

Let h (x)
 0 and h (x)
 1 be homeomorphisms of the interval [0,1] onto itself. Is it true that for any x  (-  [0,1] and almost any t  (-  (0,1) there exists a limit of a sequence

1 sum n
--  ht1 o ...o hti(x)
n i=1
for n -->  oo , where t = (0,t1t2...)2  is a binary representation of t, i.e. t =  sum   ti2-i
     i>1  and ti  (-  (0,1)?

The answer is negative. We describe the set of condensation points of the sequence in some special cases.
