Abstract:For the commutators of the parametric Marcinkiewicz integral,we show that the following inequality holds |{y∈Rn∶|μρΩ,b(f)(x)|λ}≤c‖b‖BMO∫Rn|f(x)|λ(1+log+(|f(x)|λ)), where μρΩ,b(f)(x)=(∫∞0|1tρ∫|x-y|≤tΩ(x-y)|x-y|n-ρ[b(x)-b(y)]f(y)dy|2dtt)12.
Keywords:commutators of the parametric Marcinkiewicz integral  Dini type condition  endpoint estimates
