Abstract

We consider weighted Lp(w)L^p(w) boundedness (1<p<1<p<\infty and ww a Muckenhoupt ApA_p weight) of the Calder\'{o}n commutator CΩ\mathcal C_\Omega associated with rough homogeneous kernel, under the condition ΩLq(Sn1)\Omega\in L^q(\mathbb S^{n-1}) for q0<qq_0<q\leq\infty with q0q_0 a fixed constant depending on ww. Comparing to the previous related known results (assuming ΩL(Sn1)\Omega\in L^\infty(\mathbb S^{n-1})), our result for ΩLq(Sn1)\Omega\in L^q(\mathbb S^{n-1}) with qq in the range (q0,)(q_0,\infty) is new. We also obtain a quantitative weighted bound for this CΩ\mathcal C_\Omega on Lp(w)L^p(w), which is the best known quantitative result for this class of operators.
