Abstract: This paper studied the continuity of a multi-linear commutator generated by littlewood-Paley operator and Lipschitz functions on Triebel-Lizorkin space， Hardy space and Herz-Hardy space.

Key words: Littlewood-Paley operator; multi-linear commutator; Triebel-Lizorkin space; Herz-Hardy space; Herz space; Lipschitz space

設(shè)T是Calderón-Zygmund算子，Coifman等［1］得到，交換子［b，T］(f)= bT(f) -T(bf)(b∈BMO(Rn))在Lp (Rn)的有界性(1<p<∞)．當(dāng)T是分?jǐn)?shù)次積分算子時(shí)，Chanillo［2］證明了類似的結(jié)果．Janson［3］和Paluszynski［4］在Triebel-Lizorkin空間和b屬于齊次Lipschitz空間時(shí)研究了這些結(jié)果．本文的主要目的是研究由Littlewood-Paley算子和b生成的極大多線性交換子在Triebel-Lizorkin空間，Hardy空間和Herz型Hardy空間的有界性，其中b= (b1，b2，…，bm)且函數(shù)bj∈Lipβ，1≤j≤m．

1 預(yù)備知識(shí)和定義

本文中，M(f)表示f的Hardy-Littlewood極大函數(shù)，且記Mp(f)=(M(fp))1/p對(duì)00和p>l，令Fβ，

SymboleB@ p為齊次Tribel-Lizorkin空間；用Lipβ(Rn)表示Lipschitz空間，函數(shù)f滿足

這就完成了定理3的證明．
