Global minimizers of a large class of anisotropic attractive‐repulsive interaction energies in 2D

open access: yesCommunications on Pure and Applied Mathematics, Volume 77, Issue 2, Page 1353-1404, February 2024.
Abstract We study a large family of Riesz‐type singular interaction potentials with anisotropy in two dimensions. Their associated global energy minimizers are given by explicit formulas whose supports are determined by ellipses under certain assumptions.

Quantitative weighted estimates for Rubio de Francia's Littlewood--Paley square function

open access: yes, 2019
We consider the Rubio de Francia's Littlewood--Paley square function associated with an arbitrary family of intervals in $\mathbb{R}$ with finite overlapping. Quantitative weighted estimates are obtained for this operator.

The Littlewood–Paley Theory: A Common Thread of Many Works in Nonlinear Analysis

open access: yesEMS Newsletter, 2019
In this article we present the Littlewood-Paley theory and illustrate the effectiveness of this microlocal analysis tool in the study of partial differential equations, in a context which is the least technical possible.

Discrete harmonic analysis associated with ultraspherical expansions

open access: yes, 2015
We study discrete harmonic analysis associated with ultraspherical orthogonal functions. We establish weighted l^p-boundedness properties of maximal operators and Littlewood-Paley g-functions defined by Poisson and heat semigroups generated by certain ...
