ErdÅs--Falconer distance conjecture from an analytic perspective

Le Quang Ham, Dung The Tran

Let $q$ be an odd prime power and let $V=\F_q^{2m}$, equipped with $Q(x)=x_1^2+\cdots+x_{2m}^2$. We develop a semidefinite Delsarte framework for the two-set ErdÅs--Falconer…

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…

On a theorem of Mattila in the p-adic setting

Boqing Xue, Thang Pham, Le Q. Hung +2

Let $A, B$ be subsets of $(Z / p^{r} Z)^{2}$ . In this note, we provide conditions on the densities of $A$ and $B$ such that $∣ g A - B ∣ ≫ p^{2 r}$ for a positive proportion…
