A new type of superorthogonality
Philip T. Gressman, Lillian B. Pierce, Joris Roos +1
We provide a simple criterion on a family of functions that implies a square function estimate on for every even integer . This defines a new type of superorthogona…
Endpoint sparse domination for classes of multiplier transformations
David Beltran, Joris Roos, Andreas Seeger
We prove endpoint results for sparse domination of translation invariant multiscale operators. The results are formulated in terms of dilation invariant classes of Fourier multipli…
A new proof of an inequality of Bourgain
Polona Durcik, Joris Roos
The purpose of this short note is to demonstrate how some techniques from additive combinatorics recently developed by Peluse and Peluse-Prendiville can be applied to give an alter…
Spherical maximal operators on Heisenberg groups: Restricted dilation sets
Joris Roos, Andreas Seeger, Rajula Srivastava
Consider spherical means on the Heisenberg group with a codimension two incidence relation, and associated spherical local maximal functions where the dilations are restrict…
