Linear independence of linear forms in polylogarithms
Annali della Scuola Normale Superiore di Pisa - Classe di Scienze, Série 5, Tome 5 (2006) no. 1, pp. 1-11.

For x, |x|<1, s, let Li s (x) be the s-th polylogarithm of x. We prove that for any non-zero algebraic number α such that |α|<1, the (α)-vector space spanned by 1, Li 1 (α), Li 2 (α), has infinite dimension. This result extends a previous one by Rivoal for rational α. The main tool is a method introduced by Fischler and Rivoal, which shows the coefficients of the polylogarithms in the relevant series to be the unique solution of a suitable Padé approximation problem.
