Weighted variational inequalities for the fractional Dunkl heat semigroup
Suman Mukherjee
We investigate the convergence properties of the family of operators $$ \mathcal{T}_{\bf N} f(x)=\sum_{j=N_1}^{N_2} v_j\Bigl( e^{-a_{j+1}(-Δ_k)^s}f(x) - e^{-a_j(-Δ_k)^s}f(x) \Bigr)…

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…
