缺项傅里叶级数与紧李群的定性测不准原理

Lacunary Fourier series and a qualitative uncertainty principle for compact Lie groups

E K Narayanan, A Sitaram

摘要:

在紧连通半单李群$G$上定义缺项傅里叶级数.若$f \in L^1(G)$具有缺傅里叶级数,且在非空开集上为零,则证明了$f$同零.这可以被看作是一个定性的不确定性原则。

英文摘要:

We define lacunary Fourier series on a compact connected semisimple Lie group $G$. If $f \in L^1(G)$ has lacunary Fourier series, and vanishes on a non empty open set, then we prove that $f$ vanishes identically. This may be viewed as a qualitative uncertainty principle.
