Variation and oscillation inequalities for commutators in two-weight setting
AbstractThis paper studies the two-weight estimates of variation and oscillation operators for commutators of singular integrals with weighted {\mathrm{BMO}} functions. A new characterization of weighted {\mathrm{BMO}} spaces via the boundedness of variation and oscillation operators for the iterated commutators of Calderón–Zygmund singular integrals in the two-weight setting is given.
