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 $R^{3}$ . In particular, we show that $n$ points on such a surface span $Ω\left(n…

Distinct distances in the complex plane

Adam Sheffer, Joshua Zahl

We prove that if $P$ is a set of $n$ points in $C^{2}$ , then either the points in $P$ determine $Ω (n^{1 - ε})$ complex distances, or $P$ is contained in a line with slope $\pm…
