Calderon-type commutators and chamber lifting in the Dunkl setting

Yongsheng Han, Ming-Yi Lee, Ji Li +2

Let $G$ be a finite reflection group, and let $T_j$, ${\Delta }_{\kappa }$, and $d\omega$ denote its Dunkl operators, Laplacian, and measure, respectively. Write ${\mathcal{R}}_j=-T_j(-{\Delta }_{\kappa }{)}^{-1/2}$ for th…
