摘要

摘要我们讨论了在$\mathbb{Q}_p$域上$\mathbb{Q}_p$-adic数的紧小波框架的近似问题。对于作者早先构造的域（\mathbb{Q}p\ ）中的紧小波框架，我们从具有对数权重的 Sobolev 空间中得到了函数的近似估计值。

On Approximation by Tight Wavelet Frames on the Field of $$p$$ -Adic Numbers

Abstract

We discuss the problem on approximation by tight wavelet frames on the field $\mathbb{Q}_p$ of $p$ -adic numbers. For tight frames in the field $\mathbb{Q}p$ , constructed earlier by the authors, we obtain approximation estimates for functions from Sobolev spaces with logarithmic weight.
