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 $π^V:\mathbb{F…

On a radial projection conjecture and pinned directions in finite spaces

Paige Bright, Ben Lund, Thang Pham

We give upper bounds on the number of exceptional radial projections of arbitrary subsets of vector spaces over finite fields. Our bounds do not depend on the dimension of the ambi…

Intersection patterns and connections to distance problems

Thang Pham, Semin Yoo

Let $A$ and $B$ be sets in a finite vector space. In this paper, we study the magnitude of the set $A \cap f (B)$ , where $f$ runs through a set of transformations. More precisely, we…
