沿Teichmuller测地线的曲线长度是拟凸的

Length of a curve is quasi-convex along a Teichmuller geodesic

Anna Lenzhen, Kasra Rafi

摘要:

证明了对任意简单闭曲线α,α的极值长度和双曲长度都是沿任意Teichmuller测地线的拟凸函数.作为推论,我们得到在Teichmuller度量下的Teichmuller空间中,球是拟凸的.

英文摘要:

We show that for every simple closed curve α, the extremal length and the hyperbolic length of αare quasi-convex functions along any Teichmuller geodesic. As a corollary, we conclude that, in Teichmuller space equipped with the Teichmuller metric, balls are quasi- convex.
