Distinct Distances in Between Quadratic and Orthogonal Curves

Toby Aldape, Jingyi Liu, Gregory Pylypovych +2

We study the minimum number of distinct distances between point sets on two curves in . Assume that one curve contains points and the other points. Our main results: (…

The constant of point-line incidence constructions

Martin Balko, Adam Sheffer, Ruiwen Tang

We study a lower bound for the constant of the Szemerédi-Trotter theorem. In particular, we show that a recent infinite family of point-line configurations satisfies $I({\mathcal P…

A structural Szemerédi-Trotter Theorem for Cartesian Products

Adam Sheffer, Olivine Silier

We study configurations of points and lines that form incidences, when the point set is a Cartesian product. We prove structural properties of such configurati…

Distinct distances on non-ruled surfaces and between circles

Surya Mathialagan, Adam Sheffer

We improve the current best bound for distinct distances on non-ruled algebraic surfaces in . In particular, we show that points on such a surface span $Ω\left(n…

Distinct distances in the complex plane

Adam Sheffer, Joshua Zahl

We prove that if is a set of points in , then either the points in determine complex distances, or is contained in a line with slope $\pm…

On the Number of Discrete Chains

Eyvindur Ari Palsson, Steven Senger, Adam Sheffer

We study a generalization of Erd\H os's unit distances problem to chains of distances. Given a set of points, and a sequence of distances ,…
