Structure theorems of E(n)-Azumaya algebras

Let k be a field and E(n) be the 2 ⁿ⁺¹-dimensional pointed Hopf algebra over k constructed by Beattie, Dăscălescu and Grünenfelder [J. Algebra, 2000, 225: 743–770]. E(n) is a triangular Hopf algebra with a family of triangular structures R _M parameterized by symmetric matrices M in M _n (k). In this paper, we study the Azumaya algebras in the braided monoidal category $ E_{(n)} mathcal{M}^{R_M } $ E_{(n)} mathcal{M}^{R_M } and obtain the structure theorems for Azumaya algebras in the category $ E_{(n)} mathcal{M}^{R_M } $ E_{(n)} mathcal{M}^{R_M } , where M is any symmetric n×n matrix over k.
