Multiplicative dependence among iterated values of rational functions modulo finitely generated groups

Number Theory 2018-11-14 v1 Dynamical Systems

Abstract

We study multiplicative dependence between elements in orbits ofalgebraic dynamical systems over number fields modulo a finitely generated multiplicative subgroup of the field. We obtain a series of results, many of which may be viewed as a blend of Northcott's theorem on boundedness of preperiodic points and Siegel's theorem on finiteness of solutions to SS-unit equations.
