: The paper "Effective diophantine approximation on Gm" provides deeper insights into the underlying approximation theory used to solve these equations.
The "paper" you might be recalling is likely their influential 2014 journal article, published in Acta Arithmetica , which laid the groundwork for the later book. Effective Results and Methods for Diophantine E...
