Square function estimates for discrete Radon transforms

Mariusz Mirek

Vol. 11 (2018), No. 3, 583–608
Abstract

We show p(d)-boundedness, for p (1,), of discrete singular integrals of Radon type with the aid of appropriate square function estimates, which can be thought of as a discrete counterpart of Littlewood–Paley theory. It is a very robust approach which allows us to proceed as in the continuous case.
