Reinforcing a Philosophy: Littlewood--Paley theory for the moment curve over generic local fields

Kevin Hughes

Using the Girard--Newton formulae, I give a simple proof of isotropic square function estimates for extension operators along the moment curve in generic local fields. Using Bezout…

A decoupling interpretation of an old argument for Vinogradov's Mean Value Theorem

Brian Cook, Kevin Hughes, Zane Kun Li +3

We interpret into decoupling language a refinement of a 1973 argument due to Karatsuba on Vinogradov's mean value theorem. The main goal of our argument is to answer what precisely…

Improved bounds on number fields of small degree

Theresa C. Anderson, Ayla Gafni, Kevin Hughes +5

We study the number of degree number fields with discriminant bounded by . In this article, we improve an upper bound due to Schmidt on the number of such fields that was pr…

Subcritical paucity and -improving estimates for finite-type polynomial curves

Kevin Hughes

I prove new subcritical bounds for the -improving problem along restricted subsets of a degenerate curve. The key input is a new paucity estimate for associated inhomogeneo…

Reinforcing a Philosophy: A counting approach to square functions over local fields

Kirsti D. Biggs, Julia Brandes, Kevin Hughes

In this paper, we study square functions for extension operators over finite-type, planar curves endowed with the Euclidean arclength measure. We prove new results for curves of th…

Some subcritical estimates for the -improving problem for discrete curves

Spyridon Dendrinos, Kevin Hughes, Marco Vitturi

We apply Christ's method of refinements to the -improving problem for discrete averages along polynomial curves in . Combined with certain ele…

Supercritical discrete restriction estimates for forms in many variables

Brian Cook, Kevin Hughes, Eyvindur Palsson

We prove discrete restriction estimates for a broad class of hypersurfaces and varieties of intermediate codimension. For our result about hypersurfaces, we use Bourgain's arithmet…

Discrete restriction for and related topics

Kevin Hughes, Trevor D. Wooley

Defining the truncated extension operator for a sequence with by putting \[ E{a}(α,β):=\sum_{|n|\leq N}a(n) e(αn^3 + βn), \] we obtain the conjecture…

Bounds for Lacunary maximal functions given by Birch--Magyar averages

Brian Cook, Kevin Hughes

We obtain positive and negative results concerning lacunary discrete maximal operators defined by dilations of sufficiently nonsingular hypersurfaces arising from Diophantine equat…

-improving for discrete spherical averages

Kevin Hughes

We initiate the theory of -improving inequalities for arithmetic averages over hypersurfaces and their maximal functions. In particular, we prove -improving estimat…

Improved -Boundedness for Integral -Spherical Maximal Functions

Theresa C. Anderson, Brian Cook, Kevin Hughes +1

We improve the range of -boundedness of the integral -spherical maximal functions introduced by Magyar. The previously best known bounds for the full -sp…

On the ergodic Waring--Goldbach problem

Theresa C. Anderson, Brian Cook, Kevin Hughes +1

We prove an asymptotic formula for the Fourier transform of the arithmetic surface measure associated to the Waring--Goldbach problem and provide several applications, including bo…

Discrete restriction estimates of epsilon-removal type for kth-powers and k-paraboloids

Kevin Henriot, Kevin Hughes

We obtain restriction estimates of -removal type for the set of -th powers of integers, and for discrete -dimensional surfaces of the form \[ \{ (n_1,\dots,n_d,n_1^k + \do…

The discrete spherical averages over a family of sparse sequences

Kevin Hughes

We initiate the study of the -boundedness of the arithmetic spherical maximal function over sparse sequences. We state a folklore conjecture for lacunary sequ…
