Abstract

By using properties of Markov homogeneous chains and Banach measure in N\mathrm{N}, it is proved that a relative frequency of even numbers in the sequence of nn-th coordinates of all Collatz sequences is equal to the number 23+(1)n+13×2n+1.\frac{2}{3}+\frac{(-1)^{n+1}}{3\times 2^{n+1}}. It is shown also that an analogous numerical characteristic for numbers of the form 3m+13m+1 is equal to the number 35+(1)n+115×22(n1).\frac{3}{5}+ \frac{(-1)^{n+1}}{15 \times 2^{2(n-1)}}. By using these formulas it is proved that under Collatz conjecture the Collatz mapping has no an asymptotic mixing property (mod3)\pmod{3}. It is constructed also an example of a real-valued function on the cartesian product N2N^2 of the set of all natural numbers NN such that an equality its repeated integrals (with respect to Banach measure in NN) implies that Collatz conjecture fails. In addition, it is demonstrated that Collatz conjecture fails for supernatural numbers.
