奇异分布、支撑维数与傅里叶变换的对称性

Singular distributions, dimension of support, and symmetry of Fourier transform

Gady Kozma, Alexander Olevskii

摘要:

我们研究的“傅立叶对称性”的措施和分布的圆,在其支持的大小。本文的主要结果是:(1)Frostman定理的单侧推广,它将分布的傅里叶变换的衰减率与支撑的豪斯多夫维数联系起来;(2)构造了“临界”尺寸的紧集,它支撑反解析部分属于l ^2的分布(甚至是伪函数)。我们还给出了非对称性的例子,这可能会发生的措施与“小”的支持。提出了一些悬而未决的问题。

英文摘要:

We study the "Fourier symmetry" of measures and distributions on the circle, in relation with the size of their supports. The main results of this paper are: (1) A one-side extension of Frostman's theorem, which connects the rate of decay of Fourier transform of a distribution with the Hausdorff dimension of the support; (2) A construction of compacts of "critical" size, which support distributions (even pseudo-functions) with anti-analytic part belonging to l^2. We also give examples of non-symmetry which may occur for measures with "small" support. A number of open questions are stated.
