- 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.
