Abstract

In this work, we consider the Dunkl operator on the real line , defined for by A Cinfin-function f on , is said to be mean-periodic function associated with the Dunkl operator Dk if there exists a nonzero distribution mu on with compact support such that where *k denotes the convolution associated with the Dunkl operator Dk. We characterize the solutions of these equations and we study the expansion of a mean-periodic function in series with respect to appropriate exponential monomials. Finally, we give some applications.
