Abstract:All finite orbits of polynomial mappings in one variable in rings of integers of quadratic number fields are determined. The largest such orbit has seven elements and lies in the third cyclotomic field. 2000 Mathematics Subject Classification Primary—11R09, 11R11, 37F10
Keywords:Polynomial maps  Polynomial cycles  Finite polynomial orbits  Quadratic integers
