Abstract

Let p(·): ℝn → (0, ∞] be a variable exponent function satisfying the globally log-Hölder continuous condition and A a general expansive matrix on ℝn. Let H p(·)A (ℝn) be the variable anisotropic Hardy space associated with A. In this paper, via first establishing a criterion for affirming some functions being in the space H p(·)A (ℝn), the authors obtain several equivalent characterizations of H p(·)A (ℝn) in terms of the so-called tight frame multiwavelets, which extend the well-known wavelet characterizations of classical Hardy spaces. In particular, these wavelet characterizations are shown without the help of Peetre maximal operators.

变各向异性Hardy空间的小波表征
设p(·):∈n→(0,∞)是满足全局log-Hölder连续条件的变指数函数,a是∈n上的一般可扩展矩阵。设H p(·)A(∈n)是与A相关的变各向异性Hardy空间。本文首先建立了在空间H p(·)A(∈n)中某些函数存在的判据,得到了H p(·)A(∈n)在紧框架多小波中的几个等价表征。扩展了经典Hardy空间中众所周知的小波表征。特别地,这些小波特征是在没有Peetre极大算子的帮助下显示的。

期刊介绍: Acta Mathematica Sinica, established by the Chinese Mathematical Society in 1936, is the first and the best mathematical journal in China. In 1985, Acta Mathematica Sinica is divided into English Series and Chinese Series. The English Series is a monthly journal, publishing significant research papers from all branches of pure and applied mathematics. It provides authoritative reviews of current developments in mathematical research. Contributions are invited from researchers from all over the world.
