Weighted Weak Type Estimates for Commutators of Fractional Integrals on Spaces of Homogeneous Type

在齐型空间上,建立了关于分数次积分算子与BMO函数生成的交换子的加权弱型端点估计,并运用此估计式得到交换子的一个双权弱型估计。

A weighted weak type endpoint estimate is established for the maximal operator associated with the commutator generated by fractional integral operator and BMO function on spaces of homogeneous type. As an application, a two-weight weak type norm inequality for the commutator is obtained.
