Fractional Leibniz rules for the Dunkl Laplacian in Besov and Triebel--Lizorkin spaces

The Anh Bui, Xueting Han, Suman Mukherjee

Let $L$ be the Dunkl Laplacian on the Euclidean space $R^{N}$ associated with a normalized root system $R$ and a multiplicity function $k (I^½) \geq 0$ , $I^½ \in R$ . We establish…

Large time behaviour of the fractional heat equation associated with the Dunkl Laplacian

Suman Mukherjee

We consider the fractional heat equation associated with the Dunkl Laplacian and prove that the weak solutions to this equation converge to the fundamental solution as time becomes…
