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…
