双线性奇异积分算子分解子的compactness特征

Characterization of compactness of commutators of bilinear singular integral operators

Lucas Chaffee, Peng Chen, Yanchang Han, Rodolfo Torres, Lesley A. Ward

摘要:

在$cmo$中,双线性Calderón-Zygmund算子和带符号的逐点乘法的分解子是Lebesgue空间乘积上的双线性紧算子.这项工作表明,对于某些非退化的Calderón-Zygmund算子,符号在$cmo$中不仅是充分的,而且实际上是必要的。

英文摘要:

The commutators of bilinear Calderón-Zygmund operators and point-wise multiplication with a symbol in $cmo$ are bilinear compact operators on product of Lebesgue spaces. This work shows that, for certain non-degenerate Calderón-Zygmund operators, the symbol being in $cmo$ is not only sufficient but actually necessary for the compactness of the commutators.
