$S$-unit equation in two variables and Pad\'{e} approximations

Number Theory 2024-06-19 v1

Abstract

In this article, we use Pad\'{e} approximations constructed for binomial functions, to give a new upper bound for the number of the solutions of the SS-unit equation. Combining explicit formulae of these Pad\'{e} approximants with a simple argument relying on Mahler measure and on the local height, we refine the bound due to J.-H. Evertse.
