A constructive approach to a conjecture by Voskresenskii

Algebraic Geometry 2017-04-19 v2

Abstract

Voskresenskii conjectured that stably rational tori are rational. Klyachko proved this assertion for a wide class of tori by general principles. We re-prove Klyachko's result by providing simple explicit birational isomorphisms, and elaborate on some links to torus-based cryptography.
