Riesz transform on eventually Gaussian local trees

Fabrice Baudoin, Aobo Chen, Li Chen

We study the Riesz transform $R = \partial (- Δ)^{- \frac{1}{2}}$ on uniform local trees, metric measure spaces that are locally real trees and whose canonical Dirichlet form…

Riesz transforms on the Vicsek set

Fabrice Baudoin, Aobo Chen, Li Chen

We study Riesz and reverse Riesz inequalities for the fractional powers of the Laplacian $Δ$ on the unbounded Vicsek set. The space carries its Hausdorff measure $m$ . The gradient…

Walk dimension and vanishing curve modulus in metric measure spaces

Aobo Chen

On a regular local $p$ -Dirichlet space supporting a Poincaré inequality and a capacity upper bound, we characterize the existence of curve families of positive $p$ -modulus in terms…
