摘要:

It is well known that the commutator Tb of the Calder´on-Zygmund singular integral operator is bounded on Lp(Rn) for 1 < p < +∞ if and only if b ∈ BMO [1]. On the other hand, the commutator Tb is bounded from H1(Rn) into L1(Rn) only if the function b is a constant [2]. In this article, we will discuss the boundedness of commutator of certain pseudo-differential operators on Hardy spaces H1. Let Tσ be the operators that its symbol is S01,δ with 0 ≤δ < 1, if b∈ LMO1, then, the commutator [b, Tσ] is bounded from H1(Rn) into L1(Rn) and from L1(Rn) into BMO(Rn); If [b, Tσ ] is bounded from H1(Rn) into L1(Rn) or L1(Rn) into BMO(Rn), then, ∈ LMOloc.

Abstract:

It is well known that the commutator Tb of the Calder´on-Zygmund singular integral operator is bounded on Lp(Rn) for 1 < p < +∞ if and only if b ∈ BMO [1]. On the other hand, the commutator Tb is bounded from H1(Rn) into L1(Rn) only if the function b is a constant [2]. In this article, we will discuss the boundedness of commutator of certain pseudo-differential operators on Hardy spaces H1. Let Tσ be the operators that its symbol is S01,δ with 0 ≤δ < 1, if b∈ LMO1, then, the commutator [b, Tσ] is bounded from H1(Rn) into L1(Rn) and from L1(Rn) into BMO(Rn); If [b, Tσ ] is bounded from H1(Rn) into L1(Rn) or L1(Rn) into BMO(Rn), then, ∈ LMOloc.

Key words: Hardy space, commutator, Pseudo-differential operator, LMO space
