具有小拟周期Verblunsky系数的CMV矩阵的Absolutely Continuous谱

Absolutely Continuous Spectrum for CMV Matrices With Small Quasi-Periodic Verblunsky Coefficients

Long Li, David Damanik, Qi Zhou

摘要:

我们考虑标准和扩展CMV矩阵与小的准周期Verblunsky系数,并表明,在其本质谱,所有的谱测度措施是纯粹绝对连续的。这回答了Barry Simon在2005年提出的一个问题。

英文摘要:

We consider standard and extended CMV matrices with small quasi-periodic Verblunsky coefficients and show that on their essential spectrum, all spectral measures are purely absolutely continuous. This answers a question of Barry Simon from 2005.
