Upper and lower bounds for Dunkl heat kernel

Jacek Dziubański, Agnieszka Hejna

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

Dimension-free $L^{p}$ estimates for vectors of Riesz transforms in the rational Dunkl setting

Agnieszka Hejna

In this article, we prove dimension-free upper bound for the $L^{p}$ -norms of the vector of Riesz transforms in the rational Dunkl setting. Our main technique is Bellman function met…
