An $L^{4}$ maximal estimate for quadratic Weyl sums

Alex Barron

We show that $0 < t < 1 sup n = 1 \sum N e^{2 π i (n (\cdot) + n^{2} t)}_{L^{4} ([0, 1])} \leq C_{ε} N^{3/4 + ε}$ and discuss some applications to the theory…

Fourier decay of fractal measures on hyperboloids

Alex Barron, M. Burak Erdogan, Terence L. J. Harris

Let $μ$ be an $α$ -dimensional probability measure. We prove new upper and lower bounds on the decay rate of hyperbolic averages of the Fourier transform $μ$ . More precisely…

Restriction estimates for hyperboloids in higher dimensions via bilinear estimates

Alex Barron

Let $H$ be a $(d - 1)$ -dimensonal hyperbolic paraboloid in $R^{d}$ and let $E f$ be the Fourier extension operator associated to $H,$ with $f$ supported in $B…

Sparse domination and the strong maximal function

Alex Barron, Jose M. Conde-Alonso, Yumeng Ou +1

We study the problem of dominating the dyadic strong maximal function by $(1, 1)$ -type sparse forms based on rectangles with sides parallel to the axes, and show that such dominati…

Sparse Domination for Bi-Parameter Operators Using Square Functions

Alexander Barron, Jill Pipher

Let $S$ be the dyadic bi-parameter square function $S f (x)^{2} = R \in D \sum ∣ ⟨ f, h_{R} ⟩ ∣^{2} \frac{1 _{R} ( x )}{∣ R ∣} .$ We prove that if $T$ is a bi-parame…
