Littlewood-Paley算子的模Orlicz不等式

Modular Orlicz Inequalities for the Littlewood-Paley Functions

对一般的Orlicz函数类,得到了Littlewood-Paley函数的模Orlicz不等式的充分必要条件.

In the paper under review the necessary and sufficient conditions for the modular Orlicz inequalities to take place for the Littlewood - Paley functions are obtained. These conditions deal with the generating functions of the Orlicz class.
