On two affine-like dynamical systems in a local field. (English) Zbl 1273.37046

The paper consists of two parts. The first of them is devoted to the dynamical system on a local field corresponding to the mapping \(x\mapsto x^{p^n}+a\) where \(a\) is a fixed element of the field. This setting extends, on the one hand, the case of monomial dynamical systems [A. Yu. Khrennikov and M. Nilsson, \(p\)-adic deterministic and random dynamics. Dordrecht: Kluwer (2004; Zbl 1135.37003)] and, on the other hand, the case of affine dynamical systems [A.-H. Fan and Y. Fares, Arch. Math. 96, No. 5, 423–434 (2011; Zbl 1214.11134)]. The authors study minimal subsets with respect to this dynamical system, which happen to be cycles, and give their complete description.
In the second part, the authors consider the case of a local field of a positive characteristic (more specifically, the case of a finite place of the corresponding global field) and define a dynamical system indexed not by natural numbers, as in all the existing papers on \(p\)-adic dynamics, but by elements of the ring of integers. The definition involves the Carlitz module and reflects the number-theoretic nature of the objects. For this case too, a description of orbits and minimal sets is given; properties of subsystems induced on minimal sets are studied.
