Abstract

Let KK be a number field of degree d3d\geq 3 and fix ss multiplicatively independent algebraic integers γ1,,γsK\gamma_1, \dots, \gamma_s \in K^* that fulfil some technical requirements, which can be vastly simplified to Q\mathbb{Q}-linearly independence, given Schanuel's conjecture. We then consider the twisted Thue equation NK/Q(Xγ1t1γstsY)=1, \left|N_{K/\mathbb{Q}}\left(X-\gamma_1^{t_1}\cdots\gamma_s^{t_s}Y\right)\right| = 1, and prove that it has only finitely many solutions (x,y,(t1,,ts))(x,y, (t_1, \dots, t_s) ) with xy0xy \neq 0 and Q(γ1t1γsts)=K\mathbb{Q}\left( \gamma_1^{t_1}\cdots \gamma_s^{t_s} \right) = K, all of which are effectively computable.
