Les récents progrès sur le problème de la 2-tour de Hilbert des corps de nombres portent sur l’infinitude – en particulier pour les corps quadratiques – quand le groupe des classes a un grand 4-rang. Généralisant à tout nombre premier , nous utilisons les inégalités de type Golod-Safarevic afin d’analyser la contribution du -rang du groupe des classes à l’étude de la -tour de Hilbert. Nous apportons également des résultats partiels en direction de l’infinitude de le -tour de Hilbert des corps quadratiques réels lorsque que le -rang du groupe des classes vaut .
Much recent progress in the 2-class field tower problem revolves around demonstrating infinite such towers for fields – in particular, quadratic fields – whose class groups have large 4-ranks. Generalizing to all primes, we use Golod-Safarevic-type inequalities to analyse the source of the -rank of the class group as a quantity of relevance in the -class field tower problem. We also make significant partial progress toward demonstrating that all real quadratic number fields whose class groups have a 2-rank of 5 must have an infinite 2-class field tower.
