Simultaneous popular polynomial differences in higher dimensions

Guo-Dong Hong

We extend the simultaneous popular polynomial difference theorem of Conlon, Dong, and the author to polynomial shifts along prescribed directions in . Let $P_1,\ldo…

Simultaneous popular polynomial differences over finite fields

David Conlon, Dingding Dong, Guo-Dong Hong

Green's popular difference theorem says that for every \(\varepsilon>0\), all sufficiently large primes \(p\), and every set \(A\subseteq\mathbb F_p\) of density \(α\), there exist…

Peres--Schlag's nonempty-interior problem and a shifted-product variant for product sets

Guo-Dong Hong, Chong-Wei Liang, Chun-Yen Shen

We study finite-field analogues of the Peres--Schlag nonempty-interior problem for product sets. Given \(A\subseteq\mathbb F_p\), we ask when a suitable one-dimensional linear imag…

On the Peres--Schlag orthogonal projection problem and Kakeya-type sets

Guo-Dong Hong, Chong-Wei Liang, Chun-Yen Shen

We investigate the Peres--Schlag nonempty interior problem for orthogonal projections in both the finite-field and Euclidean settings. Over finite fields , we employ…

On weighted multilinear polynomial averages in finite fields

Guo-Dong Hong

We study the weighted multilinear polynomial averages in finite fields. The essential ingredient is the -norm control of the corresponding weighted multilinear polynomial aver…

A study guide for "On the Hausdorff dimension of Furstenberg sets and orthogonal projections in the plane" after T. Orponen and P. Shmerkin

Jacob B. Fiedler, Guo-Dong Hong, Donggeun Ryou +1

This article is a study guide for ``On the Hausdorff dimension of Furstenberg sets and orthogonal projections in the plane" by Orponen and Shmerkin. We begin by introducing Fursten…

Three term rational function progressions in finite fields

Guo-Dong Hong, Zi Li Lim

Let be rational functions such that and the constant function are linearly independent over , we prove an asymptotic formul…

The Group Action Method and Radial Projection

Guo-Dong Hong, Chun-Yen Shen

The group action methods have been playing an important role in recent studies about the configuration problems inside a compact set in Euclidean spaces with given Hausdorff di…
