Simple geodesics in closed hyperbolic manifolds

Qiliang Luo, Vladimir Marković

Given any closed hyperbolic n-manifold M ( $n \geq 3$ ), we show that for a fixed $κ > \frac{3}{n - 2}$ , a random closed geodesic of length close to r has the collar of width $r^{- κ}$ when…

On the minimal diameter of finite covers

Yifei Cai, Qiliang Luo

We prove that every closed hyperbolic surface admits a sequence of finite covers with asymptotically optimal diameters.

The Effective Ehrenpreis Conjecture

Qiliang Luo

Let $M$ and $N$ be two closed hyperbolic Riemann surfaces. The Ehrenpreis Conjecture (proved by Kahn-Markovic) asserts that for any $ε > 0$ there are finite covers $M_{ε} \to M$ , and $N…

Unique extremality of affine maps on plane domains

Qiliang Luo, Vladimir Marković

We prove that affine maps are uniquely extremal quasiconformal maps on the complement of a well distribute set in the complex plane answering a conjecture from \cite{markovic}. We…
