证明了Zorich-Kontsevich猜想:紧Riemann曲面上Abel微分的模空间(层的任何连通分支)上的Teichmüller流的非平凡Lyapunov指数都是不同的.根据Zorich和Kontsevich以前的工作,这意味着存在描述典型平移表面中垂直叶理的同调行为的完全渐近拉格朗日旗。
We prove the Zorich–Kontsevich conjecture that the non-trivial Lyapunov exponents of the Teichmüller ow on (any connected component of a stratum of) the moduli space of Abelian differentials on compact Riemann surfaces are all distinct. By previous work of Zorich and Kontsevich, this implies the existence of the complete asymptotic Lagrangian flag describing the behavior in homology of the vertical foliation in a typical translation surface.
