运用Herz型Hardy空间的原子和分子分解理论,对Littlewood-Paley算子及其交换子进行了讨论,证明了Littlewood-Paley算子gψ及其与BMO函数生成的交换子gψ,b在Herz型Hardy空间上的有界性.
The Littlewood-Paley operators and its commutators were discussed.By the atomic and molecular decompositions of Herz-type Hardy spaces,the boundedness of the Littlewood-Paley operator gψ and the commutator gψ,b on Herz-type Hardy spaces are obtained.
