报告摘要:

  We survey the paper Les constantes locales de l'equation fonctionnelle de la fonction L d'Artin d'une representation orthogonale of P. Deligne.This paper relates the epsilon-factor of a special orthogonal Galois representation to the question of whether the representation can be lifted to the Spin group. The point is that the second Stiefel-Whitney classes of zero-dimensional virtual representations share the same defining properties as the local constants evaluated at s=1/2.
