Abstract

We provide a surface density threshold to guarantee mobile sampling in terms of the surface density of the set. This threshold is sharp if the Fourier transform is supported in either a ball or a cube, and further examples in the two-dimensional case where the result is sharp are given.

从表面密度看移动采样的充分条件

我们提供了一个表面密度阈值，以保证根据集合的表面密度进行移动采样。如果傅立叶变换在球或立方体中得到支持，那么这个阈值就会很尖锐，我们还给出了二维情况下结果很尖锐的例子。
