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…

Sum-product estimates over arbitrary finite fields

Doowon Koh, Sujin Lee, Thang Pham +1

In this paper we prove some results on sum-product estimates over arbitrary finite fields. More precisely, we show that for sufficiently small sets $A \subset F_{q}$ we have…
