Abstract
A beautiful and meaningful harmonic analysis has been constructed on the Euclidean space R𝑑 with Dunkl weight. The classical Fourier analysis on R𝑑 corresponds to the weightless case.
The Dunkl–Riesz potential and the Dunkl–Riesz transforms play an important role in the Dunkl harmonic analysis. In particular, they allow one to prove the Sobolev type inequalities for
the Dunkl gradient. Earlier we proved (𝐿𝑞,𝐿𝑝)-inequalities for the Dunkl–Riesz potential with two radial piecewise power weights. For the Dunkl–Riesz transforms, we proved 𝐿𝑝-inequality
with one radial power weight and, as a consequence, we obtained (𝐿𝑞,𝐿𝑝)-inequalities for the Dunkl gradient with two radial power weights. In this paper, these results for the Dunkl–Riesz transforms and the Dunkl gradient for radial power weights are generalized to the case of radial piecewise power weights.
