Random zero sets with local growth guarantees

Alan Chang, Assaf Naor, Kevin Ren

We prove that if $(M, d)$ is an $n$ -point metric space that embeds quasisymmetrically into a Hilbert space, then for every $τ > 0$ there is a random subset $Z$ of…

Paige Bright, Yuqiu Fu, Kevin Ren

We generalize the recent results on radial projections by Orponen, Shmerkin, Wang using two different methods. In particular, we show that given $X, Y \subset R^{n}$ Borel set…
