## Abstract

For $b∈BMO(R_{n})$ and $k∈N$, the $k$-th order maximal commutator of the singular integral operator $T$ with rough variable kernels is defined by

In this paper the authors prove that the $k$-th order maximal commutator $T_{b,k}$ is a bounded operator on $L_{2}(R_{n})$ if $Ω$ satisfies the same conditions given by Calderón and Zygmund. Moreover, the $L_{2}$-boundedness of the $k$-th order commutator of the rough maximal operator $M_{Ω}$ with variable kernel, which is defined by

is also given here. These results obtained in this paper are substantial improvement and extension of some known results.
