  • Chapter

Part of the book series: Progress in Mathematics ((PM,volume 81))

Abstract

Nous allons exposer la preuve du résultat suivant, obtenue par G. A. Margulis en 1987 ([6], [7], [8]): THEOREME A. Soit B une forme quadratique sur R n , indéfinie, non dégénérée et irrationnelle (non multiple d’une forme entiére). Alors |B|prend des valeurs arbitrairement petites sur Z n\{0}.
