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
     
-adic numbers and complex 
     
-adic numbers. Already the simplest 
     
-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 
     
 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…
