Let b = (b1,…,bm) be a finite family of locally integrable functions. Then, we introduce generalized higher commutator of Marcinkiwicz integral as follows:( μΩ^b^→(f)(x)=(∫ 0^∞|FΩ^b^→,t(f)(x)|^2...

Two pointwise estimates relating the maximal multilinear singular integral operators and some classical maximal operators are established. These pointwise estimates imply the rearrangement estimate and the BLO(Rn) est...
In this paper, the authors study the multilinear operators with Dini Kernel and obtain their boundedness from Herz spaces to Herz-type Hardy spaces. Moreover, the authors also consider the corresponding fractional ope...
