Riesz Transforms Characterizations of Hardy Spaces \(H^1\) for the Rational Dunkl Setting and Multidimensional Bessel Operators

  • Jacek Dziubański


We characterize the Hardy space \(H^1\) in the rational Dunkl setting associated with the reflection group \(\mathbb {Z}_2^n\) by means of special Riesz transforms. As a corollary we obtain Riesz transforms characterization of \(H^1\) for product of Bessel operators in \((0,\infty )^n\).
