论文摘要
在本文中，我们通过稀疏操作员，Riesz电位和分数最大运算符的紧凑型，建立了加权$ \ rm {vmo} $ spaces的新特征，与经典的$ \ rm {vmo} $ spaces不同至关重要。即使在未加权的环境中，我们的一些结果也是新的。
In this paper, we establish a new characterization of weighted $\rm{VMO}$ spaces, which are essential different from the classical $\rm{VMO}$ spaces, via the compactness of sparse operators, commutators of Riesz potentials and fractional maximal operators. Some of our results are new even in unweighted setting.
