Some consequences of Frobenius descent for torsors

Algebraic Geometry 2025-02-20 v1

Abstract

We show how the formalism of Frobenius descent for torsors enables to study torsors under Frobenius kernels in terms of non-commutative, Lie-valued differential forms. We pay particular attention to affine line bundles trivialized by the Frobenius.
