任意维空间连续Shearlet变换的测不准原理

Uncertainty Principles for the Continuous Shearlet Transforms in Arbitrary Space Dimensions

Firdous A. Shah, Azhar Y. Tantary

摘要:

本文的目的是为任意空间维的连续剪切波变换建立一些新的测不准原理。首先,我们推导出一个类似的Pitt不等式的连续剪切波变换,然后我们制定了Beckner的不确定性原理通过两种方法:一种是基于一个尖锐的估计,从Pitt不等式和其他经典的Beckner不等式在傅立叶域。其次,我们考虑了连续剪切波变换的一个对数Sobolev不等式,它与Beckner不等式有对偶关系。第三,我们得到了Shearlet变换的Nazarov测不准原理,它表明非平凡函数和它的Shearlet变换不可能同时被有限测度集所支持。走向高潮,我们制定的连续剪切波变换在任意空间维度的局部不确定性原则。

英文摘要:

The aim of this article is to formulate some novel uncertainty principles for the continuous shearlet transforms in arbitrary space dimensions. Firstly, we derive an analogue of the Pitt's inequality for the continuous shearlet transforms, then we formulate the Beckner's uncertainty principle via two approaches: one based on a sharp estimate from Pitt's inequality and the other from the classical Beckner's inequality in the Fourier domain. Secondly, we consider a logarithmic Sobolev inequality for the continuous shearlet transforms which has a dual relation with Beckner's inequality. Thirdly, we derive Nazarov's uncertainty principle for the shearlet transforms which shows that it is impossible for a non-trivial function and its shearlet transform to be both supported on sets of finite measure. Towards the culmination, we formulate local uncertainty principles for the continuous shearlet transforms in arbitrary space dimensions.
