introduction

  • Birman–Murakami-Wenzl algebra, a deformation of the Brauer algebra.
  • has the Hecke algebra of type A as a quotient
  • its specializations play a role in types B,C,D akin to that of the symmetric group in Schur-Weyl duality

history

  • In 1984, Vaughan Jones introduced a new polynomial invariant of link isotopy types which is called the Jones polynomial.
  • The invariants are related to the traces of irreducible representations of Hecke algebras associated with the symmetric groups.
  • In 1986, Murakami (1986) showed that the Kauffman polynomial can also be interpreted as a function F on a certain associative algebra.
  • In 1989, Birman & Wenzl (1989) constructed a two-parameter family of algebras \(C_n(\ell, m)\) with the Kauffman polynomial \(K_n(\ell, m)\) as trace after appropriate renormalization.
