Abstract

Irreducible representations of Birman-Wenzl algebras Cf(r, q) in the non-standard basis are discussed. A procedure for evaluating subduction coefficients (SDCs), or the transformation coefficients between standard and non-standard basis of Birman-Wenzl algebras, is formulated based on the linear equation method. SDCs of Cf(r, q) with f ≤ 4 are derived. Racah coefficients of the quantum groups Oq(n) and Spq(2m) can be obtained from SDCs of Birman-Wenzl algebras Cf(r, q) by using the Schur-Weyl-Brauer duality relation between Birman-Wenzl algebras Cf(r, q) and the quantum groups Oq(n) and Spq(2m).
