AI总结:

本文证明了在 genus 二曲面的 Teichmüller 空间上,Teichmüller 度量与 Carathéodory 度量相等的条件。

摘要:

令$\Tei_{g,n}$表示具有$g$个孔的黎曼面的 Teichmüller 空间。人们猜想,在 Teichmüller 盘上,Teichmüller 度量和 Carathéodory 度量相等当且仅当对应的全纯二次微分的所有零点的阶数均为偶数。Gekhtman 和 Markovic 证明了该猜想在$\Tei_{0,5}\cong \Tei_{1,2}$的情况下成立。我们确认该猜想在$\Tei_{2,0}\cong\Tei_{0,6}$的情况下也成立。

英文摘要:

Let $\Tei_{g,n}$ be the Teichmüller space of Riemann surfaces of genus $g$ with $n$ marked points. It is conjectured that the Teichmüller and Carathéodory metrics coincide on a Teichmüller disk exactly when every zero of the associated holomorphic quadratic differential (away from marked points) has even order. Gekhtman and Markovic verified this conjecture for $\Tei_{0,5}\cong \Tei_{1,2}$. We confirm the conjecture for $\Tei_{0,6}\cong\Tei_{2,0}$.
