A discrete Fourier transform associated with the affine Hecke algebra    [PDF]

J. F. van Diejen, E. Emsiz

We introduce an explicit representation of the double affine Hecke algebra (of type $A_1$) at $q=1$ that gives rise to a periodic counterpart of a well-known Fourier transform associated with the affine Hecke algebra.
