Resumen de Two-weight commutator estimates

Emil Airta

• We provide an explicit technical framework for proving very general two-weight commutator estimates in arbitrary parameters. The aim is to both clarifyexisting literature, which often explicitly focuses on two parameters only, and toextend very recent results to the full generality of arbitrary parameters. More specif-ically, we study two-weight commutator estimates { Bloom type estimates { in themulti-parameter setting involving weighted product BMO and little BMO spaces,and their combinations.
