Abstract:The affine Hecke algebra of type A has two parameters (q, t) and acts on polynomials in N variables. There are two important pairwise commuting sets of elements in the algebra: the Cherednik operators and the Jucys-Murphy elements whose simultaneous eigenfunctions are the nonsymmetric Macdonald polynomials, and basis vectors of irreducible modules of the Hecke algebra, respectively. For certain parameter values it is possible for special polynomials to be simultaneous eigenfunctions with equal corresponding ei… Show more
