Averages and maximal averages over Product j-varieties in finite fields

Doowon Koh, Sujin Lee

We study both averaging and maximal averaging problems for Product $j$ -varieties defined by $Π_{j} = {x \in F_{q}^{d} : \prod_{k = 1}^{d} x_{k} = j}$ for $j \in F_{q}^{*},$ where $\math…

Configurations of rectangles in a set in $F_{q}^{2}$

Doowon Koh, Sujin Lee, Thang Pham +1

Let $F_{q}$ be a finite field of order $q$ . In this paper, we study the distribution of rectangles in a given set in $F_{q}^{2}$ . More precisely, for any $0 < δ \leq 1$ , we…

On the finite field cone restriction conjecture in four dimensions and applications in incidence geometry

Doowon Koh, Sujin Lee, Thang Pham

The first purpose of this paper is to solve completely the finite field cone restriction conjecture in four dimensions with $- 1$ non-square. The second is to introduce a new approa…

On restriction estimates for the zero radius sphere over finite fields

Alex Iosevich, Doowon Koh, Sujin Lee +2

In this paper, we solve completely the $L^{2} \to L^{r}$ extension conjecture for the zero radius sphere over finite fields. We also obtain the sharp $L^{p} \to L^{4}$ extension estimate for…
