频谱对于n个间隔是周期性的
Spectrum is periodic for n-Intervals
摘要:
本文研究了R中多个区间并的谱集。我们表明,任何频谱与这样的谱集是周期性的,与周期的整数倍的措施集。作为结果,我们得到了这样的谱集的结构定理,并观察到一般情况下是等间隔的情况。
英文摘要:
In this paper we study spectral sets which are unions of finitely many intervals in R. We show that any spectrum associated with such a spectral set is periodic, with the period an integral multiple of the measure of the set. As a consequence we get a structure theorem for such spectral sets and observe that the generic case is that of the equal interval case.
