Multiplicative dependence of rational values modulo approximate finitely generated groups

Number Theory 2024-11-27 v3

Abstract

In this paper, we establish some finiteness results about the multiplicative dependence of rational values modulo sets which are `close' (with respect to the Weil height) to division groups of finitely generated multiplicative groups of a number field KK. For example, we show that under some conditions on rational functions f1,,fnK(X)f_1, \ldots, f_n\in K(X), there are only finitely many elements αK\alpha \in K such that f1(α),,fn(α)f_1(\alpha),\ldots,f_n(\alpha) are multiplicatively dependent modulo such sets.
