Abstract

Let (An)nN,(Bn)nNZN(A_n)_{n\in \mathbb{N}}, (B_n)_{n\in \mathbb{N}} \in \mathbb{Z}^{\mathbb{N}} be two linear-recurrent sequences that meet a dominant root condition and a few more technical requirements. We show that the split family of Thue equations X(XAnY)(XBnY)Y3=1 |X(X-A_n Y)(X-B_n Y) - Y^3| = 1 has but the trivial solutions ±{(0,1),(1,0),(An,1),(Bn,1)}\pm\{ (0,1), (1,0), (A_n,1), (B_n,1) \}, if the parameter nn is larger than some effectively computable constant.
