An L p version of Hardy's theorem for the Jacobi-Dunkl transform
In this paper, we give a generalization of Hardy's theorem for the Jacobi-Dunkl transform ℱ on ℝ. More precisely for all a > 0, b > 0 and p, q ∈ [1, +∞], we determine the measurable functions f on ℝ such that E 1/4a −1 f ∈ L α,β p (ℝ) and e bλ 2 ℱf ∈ L σ q (ℝ), where E t , t > 0, L α,β...
