摘要: 利用Hormander类的精细估计, 证明由双线性拟微分算子与Lipschitz函数和BMO函数生成的交换子在广义Morrey空间上的有界性, 进而得到双线性拟微分算子的交换子在经典Morrey空间上的有界性.

关键词: 双线性拟微分算子, BMO函数, Lipschitz函数, 交换子, Morrey空间

Abstract: By using the accurate estimates of the  Hormander class, we proved the boundedness of the commutators generated by the bilinear pseudodifferential operators and Lipschitz functions and BMO functions on the generalized Morrey spaces, and then obtained the boundedness of the commutators of the bilinear pseudodifferential operators on the classical Morrey spaces.

Key words: Morrey space, bilinear pseudodifferential operator, Lipschitz function, commutator, BMO function
