We show that the Brauer group BM(k, H Ξ½ , R s,Ξ² ) of the quasitriangular Hopf algebra (H Ξ½ , R s,Ξ² ) is a direct product of the additive group of the field k and the classical Brauer group B ΞΈ s (k, Z 2Ξ½ ) associated to the bicharacter ΞΈ s on Z 2Ξ½ defined by ΞΈ s (x, y) = Ο sxy , with Ο a 2Ξ½th root o
B be the repetitive algebra of a finite dimensional algebra B over a field K Ε½ . by the B-bimodule DB s Hom B, K , and let be the Nakayama automorphism ΛΓ΄f B. We determine the positive automorphisms of B such that the orbit algebra ΛΕ½ . Br is isomorphic to a splittable extension algebra of B by the
