Abstract:In this article, we solve the problem of constructing moduli spaces of semistable principal bundles (and singular versions of them) over smooth projective varieties over algebraically closed ground fields of positive characteristic.
Keywords:Principal bundle  Moduli space  Positive characteristic  Semistable reduction  Semistability
