ABSTRACT

We study dynamical systems in the non-Archimedean number fields (i.e., fields with non-Archimedean valuation). The main results are obtained for the fields of p  -adic numbers and complex p  -adic numbers. Already the simplest p  -adic dynamical systems have a very rich structure. There exist attractors, Siegel disks and cycles. There also appear new structures such as “fuzzy cycles.” A prime number p  plays the role of parameter of a dynamical system. The behavior of the iterations depends on this parameter very much. In fact, by changing p we can change crucially the behavior: attractors may become centers of Siegel disks and vice versa, cycles of different length may appear and disappear
