Paley-wiener theorems for the Dunkl transform and Dunkl translation operators

摘要

We use the Dunkl intertwining operator V_k and its dual 'V_k to prove a Paley-Wiener theorem for the Dunkl transform, for functions and distributions, and geometric forms of this theorem. These operators permit also to define and study Dunkl translation operators and Dunkl convolution product.
