扩张映射的随机U(1)扩张的熄灭极限定理

Quenched limit theorems for random U(1) extensions of expanding maps

Yong Moo Chung, Yushi Nakano, Jens Wittsten

摘要:

在我们以前的工作[NW 2015]中研究了环面上扩展映射的随机U(1)扩张的Lyapunov谱。利用这个结果,我们将最近的谱方法扩展到我们的部分双曲动力系统中,用于扩展映射[DFGV 2018]和双曲映射[DFGV 2019]的猝灭极限定理。利用抽象随机动力系统的相应定理,证明了环面上扩张映射的随机U(1)扩张的熄灭中心极限定理、大偏差原理和局部中心极限定理.

英文摘要:

The Lyapunov spectra of random U(1) extensions of expanding maps on the torus were investigated in our previous work [NW2015]. Using the result, we extend the recent spectral approach for quenched limit theorems for expanding maps [DFGV2018] and hyperbolic maps [DFGV2019] to our partially hyperbolic dynamics. Quenched central limit theorems, large deviations principles and local central limit theorems for random U(1) extensions of expanding maps on the torus are proved via corresponding theorems for abstract random dynamical systems.
