摘    要:利用Hardy-Lorentz空间的原子分解,借助于L^q有界性的结论,使用不等式估计,证明了Littlewood—Paley算子交换子从Hardy—Lorentz空间到弱空间L^p,∞(R^n)的有界性。此结果补充了Littlewood—Paley算子交换子有界性理论。

关 键 词:Hardy-Lorentz空间  Littlewood-Paley算子  交换子  BMO(Rn)函数

Abstract:The boundedness of commutators of Littlewood-Paley operators from certain Hardy-Lorentz spaces to L^p,∞ (R^n) space is obtained from the results of boundedness of L^q spaces by using the atomic decomposition of the Hardy-Lorentz spaces and the inequality estimates. This result complements the result of boundedness of commutators of Littlewood-Paley operators.
Keywords:Hardy-Lorentz space  Littlewood-Paley operator  commutator  BMO(R^n) function
