Additive structures imply more distances in $F_{q}^{d}$

Daewoong Cheong, Gennian Ge, Doowon Koh +3

For a set $E \subseteq F_{q}^{d}$ , the distance set is defined as $I^ (E) := {∥ x - y ∥ : x, y \in E}$ , where $∥ \cdot ∥$ denotes the stan…

A functional Loomis-Whitney type inequality in the Heisenberg group and projection theorems over finite fields

Daewoong Cheong, Thang Pham, Dung The Tran

We establish functional Loomis--Whitney type inequalities in the finite Heisenberg group $H^{n} (F_{q})$ . For $n = 1$ , we determine the sharp region of exponents $(u_1,u…

Orthogonal projections and incidence bounds in planes over prime order fields

Ben Lund, Thang Pham, Le Anh Vinh

Let $p$ be an odd prime and let $E \subset F_{p}^{2}$ with $∣ E ∣ = p^{a}$ , where $0 < a \leq 1$ . For a direction $V$ (a $1$ -dimensional subspace of $F_{p}^{2}$ ), let $Ï^V:\mathbb{…

On $L^{2}$ estimates for quadratic images of product Frostman measures

Sung-Yi Liao, Thang Pham, Chun-Yen Shen

Let $f \in R [x, y, z]$ be a fixed non-degenerate quadratic polynomial. Given an $I^\pm$ -Frostman probability measure $I^¼$ supported on $[0, 1]$ with $I^\pm \in (0, 1)$ , consider the push…

Polynomial extensions of Raimi's theorem

Norbert Hegyvari, Janos Pach, Thang Pham

Raimi's theorem guarantees the existence of a partition of $N$ into two parts with an unavoidable intersection property: for any finite coloring of $N$ , some colo…

Restricted projections in positive characteristic via Fourier extension and restriction estimates

Le Quang Ham, Do Trong Hoang, Le Quang Hung +2

Let $d \geq 3$ and $F_{q}^{d}$ be the $d$ -dimensional vector space over a finite field of order $q$ , where $q$ is an odd prime power. Let $X_{I ¨} $ be the set of lines through t…
