“…The idea of using a versal model of a G-torsor, originally due to E. Noether, has come up a number of times in the literature, notably in work of E. Fischer, D. Saltman [17], F. A. Bogomolov [1]; see [20] and [21] for further references.…”

“…This notion of generic extension has been introduced by Saltman [Sa]. His original definition of a generic extension for G over k was given in terms of Galois extension of rings [Sa,p.255]. (For the definitions of the Galois extensions of rings see [CHR]…”

“…Thus we can identify the Galois group of L /K with G . Let L = Ind Γ G (L ) [Sa,Prop.0.3]. Then the extension of K-algebras L/K is Galois with the group Γ.…”
