f-categories and Tate motives, by J. Wildeshaus
Using Beilinson's theory of f-categories, we prove that the triangulated
category of Tate motives over a field k is equivalent to the bounded derived
category of its heart, provided that k is algebraic over the rationals. This
answers a question asked by Levine.
