A discrete Fourier transform associated with the affine Hecke algebra (1209.3294v1)
Published 14 Sep 2012 in math.RT, math-ph, and math.MP
Abstract: 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.
