Mixed Tate motives over Z
... of even Tate twists (since multiple zeta values are real numbers, we need not consider odd Tate twists). In keeping with the usual terminology for multiple zeta values, we refer to the grading on HMT+ as the weight, which is one half the motivic weight. After making some choices, the motivic multipl ...

... (ii) There exists Y ∈ A∗ such that Y XY −1 = ζX. (iii) For Y as in (ii) one has E(X, ζ) = Y L = LY . Proof. (i) follows from dimk L = deg A, (ii) from the Skolem-Noether theorem, and (iii) from (i) and (ii). By a ζ-pair we understand a pair (X, Y ) of invertible elements X, Y ∈ A such that Y X = ζXY ...
