A new characterization of $\text {CMO}(\mathbb R^n)$ is established replying upon local mean oscillations. Some characterizations of iterated compact commutators on weighted Lebesgue spaces are given, which are new even in the unweighted setting for the first order commutators.

对换向器紧凑性的重新审视

$\text {CMO}(\mathbb R^n)$ 的新特征 是建立在局部平均振荡上的。给出了加权 Lebesgue 空间上的迭代紧凑交换子的一些特征,即使在一阶交换子的未加权设置中,这些特征也是新的。
