Abstract
Using a generalized spherical mean operator, we obtain a generalization of Titchmarsh’s theorem for the Dunkl transform for functions satisfying the (φ; p)-Dunkl Lipschitz condition in the space Lp(Rd; wl(x)dx), 1 < p ⩽ 2, where wl is a weight function invariant under the action of an associated reflection group.
