指数Riesz基、无理旋转的差异与BMO

Exponential Riesz bases, discrepancy of irrational rotations and BMO

Gady Kozma, Nir Lev

摘要:

研究了频率属于“简单拟代数”的指数系统的基性质。我们证明了一个丢番图条件是这样一个系统是有限区间并上L^2中的Riesz基的充要条件。为了证明,我们扩展到BMO的凯斯滕定理的差异不合理的旋转圈。

英文摘要:

We study the basis property of systems of exponentials with frequencies belonging to 'simple quasicrystals'. We show that a diophantine condition is necessary and sufficient for such a system to be a Riesz basis in L^2 on a finite union of intervals. For the proof we extend to BMO a theorem of Kesten about the discrepancy of irrational rotations of the circle.
