Query: Determinantal Construction of Orthogonal Polynomials Associated with
  Root Systems   We consider semisimple triangular operators acting in the symmetric component
of the group algebra over the weight lattice of a root system. We present a
determinantal formula for the eigenbasis of such triangular operators. This
determinantal formula gives rise to an explicit construction of the Macdonald
polynomials and of the Heckman-Opdam generalized Jacobi polynomials.
