Global coefficient ring in the nilpotence conjecture, by Joseph Gubeladze

In the recent preprint 0867 Cortiñas, Haesemeyer, Walker, and Weibel give a new proof of the nilpotence conejcture for toric varieties over a field of characteristic 0. In this note we show that the nilpotence conjecture for toric varieties is true over any regular coefficient ring containing Q.
