On sait que la méthode classique de Schneider (en une variable) permet de minorer des combinaisons linéaires de deux logarithmes de nombres algébriques avec des coefficients algébriques. Nous généralisons cette méthode en plusieurs variables pour minorer des combinaisons linéaires de plusieurs logarithmes.

Abstract

Abstract

It's well known that Schneider's classical method (involving functions of a single complex variable) yields lower bounds for linear combinations of two logarithms of algebraic numbers with algebraic coefficients. We extend this method to functions of several variables and deduce an estimate for linear combinations of several logarithms.
