摘要 本文研究了带有标准信息的各向同性Besov周期函数类的逼近问题,求得了带混淆范数的多维周期Besov函数类的Kolmogorov,Gel'fand和线性N-宽度的精确阶. This paper considers the approximation problem on periodic functions of isotropic Besov using standard information. The exact orders of Kolmogorov, Gel'fand and linear N-widths for Besov classes with mixed norms of multi-dimensional periodic functions are determined.
