R-matrix and Mickelsson algebras for orthosymplectic quantum groups
  Let $\g$ be a complex orthogonal or symplectic Lie algebra and   $\g'\subset \g$ the Lie subalgebra of rank $\rk \g'=\rk \g-1$ of the same type. We give an explicit construction of generators of the Mickelsson algebra $Z_q(\g,\g')$ in terms of Chevalley generators via the R-matrix of $U_q(\g)$.
