摘要: For $1<p<\infty$, Coifman-Rochberg-Weiss established $L^{p}$ boundedness of commutators of smooth kernels. Later, many works tried to weaken the smooth condition. In this paper, we extend these mentioned results to the case of non-homogeneous but with strong Hörmander condition. Our main skills lie in wavelet decomposition, wavelet commutators, Hardy-Littlewood maximal operator and Fefferman-Stein's vector-valued maximum function Theorem.
