Abstract

We give a classification for the irreducible u\mathfrak{u}-diagonalizable representations of the degenerate affine Hecke algebra of type G(,1,n)G(\ell,1,n). Precisely we show that such H,nH_{\ell,n}-modules are indexed by \ell-skew shapes and that the representation indexed by a skew shape DD has a basis of eigenvectors indexed by standard Young tableaux of shape DD.
