Two weight estimates for commutators of fractional integrals

Using the improved sparse domination due to Wen and Wu, we obtain the separated bump conditions, including Orlicz bumps and mixed entropy bumps. Furthermore, we derive the separated logarithmic bump for the iterated commutators of fractional integrals.

Abstract

Using the improved sparse domination due to Wen and Wu, we obtain the separated bump conditions, including Orlicz bumps and mixed entropy bumps. Furthermore, we derive the separated logarithmic bump for the iterated commutators of fractional integrals.
