论文摘要

我们考虑连续$ \ mathrm {sl}(2,\ mathbb {r})$在一般动态系统上有价值的旋转,并讨论各种统一性概念。特别是,我们提供了连续$ \ mathrm {sl}的统一单参数系列(2,\ m athbb {r})$ cocycles as $g_Δ$ -sets。然后将这些结果应用于具有动态定义电势的Schrödinger运营商。如果通过满足Boshernitzan条件的子升级给出了基本动力学,我们表明,对于通用连续采样函数,相关的Schrödinger共生对所有能量都是均匀的,而在Aperiodic情况下,频谱是零Lebesgue Measure setor setor setor set of le lebesgue测度。

We consider continuous $\mathrm{SL}(2,\mathbb{R})$ valued cocycles over general dynamical systems and discuss a variety of uniformity notions. In particular, we provide a description of uniform one-parameter families of continuous $\mathrm{SL}(2,\mathbb{R})$ cocycles as $G_δ$-sets. These results are then applied to Schrödinger operators with dynamically defined potentials. In the case where the base dynamics is given by a subshift satisfying the Boshernitzan condition, we show that for a generic continuous sampling function, the associated Schrödinger cocycles are uniform for all energies and, in the aperiodic case, the spectrum is a Cantor set of zero Lebesgue measure.
