摘要: We establish a connection between specialization of the nonsymmetric Macdonald polynomials and the Demazure characters the corresponding affine Kac-Moody algebra. This allows us to obtain a representation-theoretical interpretation coefficients the expansion specialized symmetric in the basis formed by irreducible associated finite Lie
