A note on commutators of singular integrals with $\mathrm{BMO}$ and $\mathrm{VMO}$ functions in the Dunkl setting

Jacek Dziubański, Agnieszka Hejna

On ${\mathbb{R}}^N$ equipped with a root system $R$, multiplicity function $k\ge 0$, and the associated measure $dw(\mathbf{x})=\prod_{α\in R}|\langle \mathbf{x},α\rangle|^{k(α)}\,d…
