齐型空间上奇异积分有界性的判定

Criterion of the boundedness of singular integrals on spaces of homogeneous type

Yanchang Han, Yongsheng Han, Ji Li

摘要:

众所周知,几何因素在调和分析的许多问题中起着决定性的作用。本文的主要目的是给出奇异积分在Hardy空间及其对偶空间上有界的判别准则,特别是在Coifman和Weiss意义下的齐型空间$(X, d,μ)$的$\bmo$上,其中准度量$d$可能没有正则性,测度$μ$只满足加倍性质.我们没有对拟度量和加倍测度作额外的几何假设,因此,本文的结果推广到所有相关的先前结果的完全一般性,其中对拟度量$d$和测度$μ.$都作了额外的几何假设。我们证明了Coifman和Weiss引入的原子Hardy空间与小波系数定义的Hardy空间一致,并发展了这种一般设置的分子理论。本文使用的主要工具是原子分解、最近由Auscher和Hytönen构造的正交小波基、离散Calderón型再生公式、几乎正交估计、实现各种停时参数以及Hardy空间与Carleson测度空间的对偶性。

英文摘要:

It was well known that geometric considerations enter in a decisive way in many questions of harmonic analysis. The main purpose of this paper is to provide the criterion of the boundedness for singular integrals on the Hardy spaces and as well as on its dual, particularly on $\bmo$ for spaces of homogeneous type $(X, d,μ)$ in the sense of Coifman and Weiss, where the quasi-metric $d$ may have no regularity and the measure $μ$ satisfies only the doubling property. We make no additional geometric assumptions on the quasi-metric or the doubling measure and thus, the results of this paper extend to the full generality of all related previous ones, in which the extra geometric assumptions were made on both the quasi-metric $d$ and the measure $μ.$ To achieve our goal, we prove that the atomic Hardy spaces introduced by Coifman and Weiss coincide with the Hardy spaces defined in terms of wavelet coefficients and develop the molecule theory for this general setting. The main tools used in this paper are atomic decomposition, the orthonormal wavelet basis constructed recently by Auscher and Hytönen, the discrete Calderón-type reproducing formula, the almost orthogonal estimates, implement various stopping time arguments and the duality of the Hardy spaces with the Carleson measure spaces.
