Abstract

We study the distribution of the sequence of elements of the discrete dynamical system generated by iterations of the Möbius map x ↦ (ax + b)/(cx+d) over a finite field of p elements at the moments of time that correspond to prime numbers. In particular, we obtain nontrivial estimates of exponential sums with such sequences.
