Étant donné un schéma en groupes fini modéré, nous construisons des espaces de modules de G-torseurs sur des variétés algébriques, en utilisant une version en grande dimension de la théorie des morphismes stables tordus dans les champs classifiants.
Given a finite tame group scheme , we construct compactifications of moduli spaces of -torsors on algebraic varieties, based on a higher-dimensional version of the theory of twisted stable maps to classifying stacks.
