We consider Dunkl theory on Rd associated to a finite reflection group G. We establish first an estimate for the Dunkl translation of the characteristic function of a closed ball with radius ε > 0 centered at 0. Second, we prove that the uncentered maximal function associated with the Dunkl operators is of weak-type (1, 1). We finally obtain that it is strong-type (p, p) for 1 < p ≤ +∞.
Keywords: Dunkl operators, Dunkl transform, Dunkl translations, uncentered maximal function.
