Shorter proof of dimension-free estimates for maximal Riesz transforms
Maciej Kucharski, Mateusz Kwaśnicki
We provide a shorter and more direct proof of estimates for maximal Riesz transforms (of an arbitrary order) in terms of the corresponding Riesz transforms, with a constant i…
On the dimension-free control of higher order truncated Riesz transforms by higher order Riesz transforms
Maciej Kucharski, Mateusz Kwaśnicki, Błażej Wróbel
Fix a positive integer . Let be a higher order Riesz transform of order on and let be the corresponding truncated Riesz transform. We st…
Dimension-free estimates for positivity-preserving Riesz transforms related to Schrödinger operators with certain potentials
Maciej Kucharski
We study the boundedness for Riesz transforms of the form where and is a non-negative potential with power growth…
