The quotient set of the quadratic distance set over finite fields

A Iosevich, D Koh, F Rakhmonov - Forum Mathematicum, 2024 - degruyter.com
Let 𝔽 qd be the d-dimensional vector space over the finite field 𝔽 q with q elements. For
each non-zero r in 𝔽 q and E⊂ 𝔽 qd, we define W⁢(r) as the number of quadruples (x, y, z …

[HTML][HTML] Extension theorems and a connection to the Erdős-Falconer distance problem over finite fields

D Koh, T Pham - Journal of Functional Analysis, 2021 - Elsevier
The first purpose of this paper is to provide new finite field extension theorems for
paraboloids and spheres. By using the unusual good Fourier transform of the zero sphere in …

Almost spanning distance trees in subsets of finite vector spaces

D Chakraborti, B Lund - Bulletin of the London Mathematical …, 2024 - Wiley Online Library
For d⩾ 2 d\geqslant2 and an odd prime power qq, consider the vector space F qd F_q^d
over the finite field F q F_q, where the distance between two points (x 1,…, xd) (x_1,...,x_d) …

A point-conic incidence bound and applications over Fp

A Mohammadi, T Pham, A Warren - European Journal of Combinatorics, 2023 - Elsevier
In this paper, we prove the first incidence bound for points and conics over prime fields. As
applications, we prove new results on expansion of bivariate polynomial images and on …

Parallelograms and the VC-dimension of the distance sets

T Pham - Discrete Applied Mathematics, 2024 - Elsevier
In this paper, we study the distribution of parallelograms and rhombi in a given set in the
plane over arbitrary finite fields F q 2. As an application, we improve the recent result due to …

Group action and L2-norm estimates of geometric problems

T Pham - Journal of Mathematical Analysis and Applications, 2024 - Elsevier
In 2017, by using the group theoretic approach and tools from discrete Fourier analysis,
Bennett, Hart, Iosevich, Pakianathan, and Rudnev obtained a number of results on the …

Intersection patterns and incidence theorems

T Pham, S Yoo - arXiv preprint arXiv:2304.08004, 2023 - arxiv.org
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 …

An improved point-line incidence bound over arbitrary finite fields via the VC-dimension theory

A Iosevich, T Pham, S Senger, M Tait - arXiv preprint arXiv:2303.00330, 2023 - arxiv.org
The main purpose of this paper is to prove that the point-line incidence bound due to Vinh
(2011) over arbitrary finite fields can be improved in certain ranges by using tools from the …

Packing sets in Euclidean space by affine transformations

A Iosevich, P Mattila, E Palsson, MQ Pham… - arXiv preprint arXiv …, 2024 - arxiv.org
For Borel subsets $\Theta\subset O (d)\times\mathbb {R}^ d $(the set of all rigid motions) and
$ E\subset\mathbb {R}^ d $, we define\begin {align*}\Theta (E):=\bigcup_ {(g …
