Littlewood-Paley square functions and the local Hardy space for Multi-Norm Structures on

Agnieszka Hejna, Alexander Nagel, Fulvio Ricci

Multi-norm singular integrals and Fourier multipliers were introduced in [29], and one application of these notions was a precise description of the composition of convolution oper…

Characterizations of and Fefferman-Stein decompositions of functions by systems of singular integrals in the Dunkl setting

Jacek Dziubański, Agnieszka Hejna

We extend the classical theorem of Uchiyama about constructive Fefferman-Stein decompositions of functions by systems of singular integrals to the rational Dunkl settin…

On Lipschitz spaces in the Dunkl setting -- semigroup approach

Jacek Dziubański, Agnieszka Hejna

Let be the Dunkl-Poisson semigroup associated with a root system and a multiplicity function . Analogously to the classical theory,…

A note on commutators of singular integrals with and functions in the Dunkl setting

Jacek Dziubański, Agnieszka Hejna

On equipped with a root system , multiplicity function , and the associated measure $dw(\mathbf{x})=\prod_{α\in R}|\langle \mathbf{x},α\rangle|^{k(α)}\,d…

Remarks on Dunkl translations of non-radial kernels

Jacek Dziubański, Agnieszka Hejna

On equipped with a root system and a multiplicity function , we study the generalized (Dunkl) translations of not necessarily ra…
