对于Lipschitz基变换上的Hölder共环,可能不可逆,我们证明了Oseledets定理给出的子束在任意接近1的紧测度集上是Hölder‐连续的。结果推广到向量束自同构,以及在阿贝尔微分模空间上的teichmller流上的kontsevic - zorich循环。继Chaika-Eskin最近的结果之后,我们的结果也推广到任何给定的teichm<e:1>勒盘。
For Hölder cocycles over a Lipschitz base transformation, possibly non‐invertible, we show that the subbundles given by the Oseledets Theorem are Hölder‐continuous on compact sets of measure arbitrarily close to 1. The results extend to vector bundle automorphisms, as well as to the Kontsevich–Zorich cocycle over the Teichmüller flow on the moduli space of abelian differentials. Following a recent result of Chaika–Eskin, our results also extend to any given Teichmüller disk.
