Özet
In this paper we consider the anisotropic maximal commutator Mbd and the commutator of the anisotropic maximal operator [b, Md] on the Lorentz spaces Lp,q (ℝn). We obtain necessary and sufficient conditions for the boundedness of the operators Mbd and[b, Md] on Lp,q (ℝn) when b belongs to the bounded mean oscillation space BMO(ℝn), whereby some new characterizations for certain subclasses of BMO(ℝn) are obtained.
