Hello,

Can someone provide a solution to the following problem, or give references
to related work in the litterature ?

Let f:[0,1]^n-->[0,1]^n (n>1) be a function of the form
f(x)=(P_1(x),P_2(x),...,P_n(x)) where the P_i's are polynomials.
Let's consider the iterates of f. Is the following situation possible ?

for all k, there exists an infinite number of k-cycles (by k-cycle, I mean
a cycle of length exactly k).

Generalize to rational functions instead of polynomials, and to analytic 
functions.

Thanks,

Pascal.
