... the Azumaya algebras  D X and τ ∗ ν (  D X ) are canonically equivalent. Proof. Recall that to establish an equivalence between two Azumaya al- gebras A, A  on a scheme Y (i.e. an equivalence ... paper [BMR2]. The main result is obtained for a regular Harish-Chandra central character, and the most interesting case is that of an integral Harish-Chandra central character; integral...
