A Sylvester-Gallai theorem for cubic curves

Alex Cohen, Frank de Zeeuw

We prove a variant of the Sylvester-Gallai theorem for cubics (algebraic curves of degree three): If a finite set of sufficiently many points in $R^{2}$ is not contained in…

A Sylvester-Gallai result for concurrent lines in the complex plane

Alex Cohen

We show that if a set of points in $C^{2}$ lies on a family of $m$ concurrent lines, and if one of those lines contains more than $m - 2$ points, then there is a line passing…

Poissonian correlation of higher order differences

Alex Cohen

A sequence $(x_{n})_{n = 1}^{\infty}$ on the torus $T$ exhibits Poissonian pair correlation if for all $s \geq 0$ , \begin{equation*} \lim_{N\to\infty} \frac{1}{N}\#\left\{1\leq…
