论文摘要
本文的目的是为傅立叶和短期傅立叶变换建立一些不确定性原则。此外，我们讨论了Donoho（稳定的不确定性原理）的类似物，并为短期傅立叶变换的基本支持提供了一些估计。
The aim of this paper is to establish a few uncertainty principles for the Fourier and the short-time Fourier transforms. Also, we discuss an analogue of Donoho--Stark uncertainty principle and provide some estimates for the size of the essential support of the short-time Fourier transform.
