BMO Functions Generated by Weights on Ball Banach Function Spaces

[摘要] Let be a ball Banach function space on . We introduce the class of weights . Assuming that the Hardy-Littlewood maximal function is bounded on and , we obtain that . As a consequence, we have , where is the variable exponent Lebesgue space. As an application, if a linear operator is bounded on the weighted ball Banach function space for any , then the commutator is bounded on with .
