摘要:

该文探讨了象征函数属于Hörmander类Smρδ(Rn)的拟微分算子T及其与BMO函数b生成的交换子[bT]在加权Lp空间Lpω(Rn)上的有界性问题,其中权ω属于Ap(φ),它包含了经典的Muckenhoupt权Ap(Rn).

关键词: 拟微分算子, 交换子, BMO, Ap(φ)权, 加权Lp估计

Abstract:

In this paper, we establish weighted Lp inequalities for pseudo-differential operators T and their commutators [b,T] with smooth symbols in Smρ,δ(Rn), where bBMO(Rn) and the weight ω belongs to the new class Ap(φ). It is well known that the Muckenhoupt class Ap falls within the class Ap(φ). This results extend the class of pseudo-differential operator to a wide range of m.

Key words: Pseudo-differential operator, Commutator, BMO, Ap(φ) weights, Weighted Lp estimate
