[Une classification tannakienne des torseurs sur la droite projective]
Comptes Rendus. Mathématique, Volume 356 (2018) no. 11-12, pp. 1203-1214.

Nous présentons dans cette courte Note une démonstration tannakienne du théorème de Grothendieck–Harder sur la classification des torseurs pour un groupe réductif, sur la droite projective définie sur un corps.

In this small note, we present a Tannakian proof of the theorem of Grothendieck–Harder on the classification of torsors under a reductive group on the projective line over a field.
