Query: Functional equations for transfer-matrix operators in open Hecke chain
  models   We consider integrable open chain models formulated in terms of generators of
affine Hecke algebras. The hierarchy of commutative elements (which are analogs
of the commutative transfer-matrices) are constructed by using the fusion
procedure. These elements satisfy a set of functional relations which
generalize functional relations among a family of transfer-matrices in solvable
spin chain models of U_q(gl(n|m)) type.
