Abstract: We give non-symmetric versions of the Cauchy kernel and Littlewood''s kernels, corresponding to the types A, B, C and D, of the classical groups. Defining two families of key polynomials (one of them being the Demazure characters), we show that these new kernels are diagonal in the basis of key polynomials. We define scalar products such that the two families of key polynomials are adjoint to each other. [Copyright &y& Elsevier] |
