運用了Sharp極大函數估計的方法證明了當權函數滿足一定條件時,Bochner-Riesz算子與加權BMO函數生成的交換子在加權Morrey空間上的有界性.
Bochner-Riesz算子;加權Morrey空間;加權BMO空間
經典的Morrey空間Lp,λ首先是由Morrey[1]在研究二階橢圓型偏微分方程解的局部性質時所引進的.2009年,Komori和Shirai[2]建立了加權Morrey空間Lp,κ(ω)并且研究了調和分析中一些主要算子,比如Hardy-Littlewood極大算子,Calder′on-Zygmund奇異積分算子以及分數次積分算子在這些加權Morrey空間上的有界性問題.在?n(n≥2)中階為δ>0 的Bochner-Riesz算子起初是通過Fourier變換,對Schwartz函數來定義的,


這些算子首先是由Bochner引進的,它們與多重Fourier級數的求和密切相關并且在調和分析的研究中起著很重要的作用.設b是?n上的一個局部可積函數,對于任意給定的R>0, b和所生成的交換子定義如下:








從而完成了定理的證明.

In this paper,we use a method of sharp maximal function to show the boundedness of commutator generated by Bochner-Riesz operators and weighted BMO function on the weighted Morrey spaces under appropriate conditions on the weight.
