Discrete Analysis (2019)
The sharp square function estimate with matrix weight, Discrete Analysis 2019:2, 8 pp. A central theme in harmonic analysis is to determine whether naturally occurring operators are bounded with respect to naturally occurring norms. One class of nor

We prove a multi-parameter dyadic embedding theorem for the Hardy operator on the multi-tree. We also show that for a large class of Dirichlet spaces in the bi-disc and the tri-disc, this proves the embedding theorem of those Dirichlet spaces of holo

Nicola Arcozzi, Pavel Mozolyako, Karl-Mikael Perfekt, and Giulia Sarfatti recently gave the proof of a bi-parameter Carleson embedding theorem. Their proof uses heavily the notion of capacity on the bi-tree. In this note we give another proof of a bi

For any n≥1, and any f:{−1,1}n→R, we have RE(f+i|∇f|)3/2≤R(Ef)3/2, where z3/2 for z=x+iy is taken with principal branch, and R denotes the real part. We show an application of this inequality: it sharpens a well-known inequality of Beckner.

The first author showed in [18] that the Hilbert transform lies in the closed convex hull of dyadic singular operators -so-called dyadic shifts. We show here that the same is true in any $\mathbb{R}^n$ -the Riesz transforms can be obtained as the res
