摘要
主要构造出了一类s_d-集但非W_s_d-集.同时,我们使用一种新方法,推广了一些已知的结果.基于这些结果,系统地揭示了s_d-尺度函数的傅里叶变换的支集与闭球的关系.
This paper mainly constructs a class of Sd sets, but not Wsd sets. Furthermore, we generalize some known result by using a new method. On the basis of these results, we systematically reveal the relationship between support of Fourier Transform of sd-scaling functions and closed balls.
