Soit un -fibré principal différentiable sur une variété ( un groupe de Lie compact). Étant donné une action d’un groupe de Lie compact sur , on se pose la question de savoir si elle provient d’une action sur le fibré . L’originalité de ce travail est de relier ce problème à l’existence de points fixes pour les actions de que l’on induit naturellement sur divers espaces de modules de -connexions sur .
Let be a smooth -principal bundle over a manifold ( being a compact Lie group). Given an action of a compact Lie group on , one asks the question whether it comes from an action on the bundle . In this paper, this question is shown to be essentially equivalent to the existence of fixed points for the naturally induced actions of on various moduli spaces of -connections on .
