Hardy type estimates for commutators of singular integrals

  • Yongzhong Sun
  • Weiyi Su


In this paper we study the Hardy type estimates for commutators Tb of standard Calderón-Zygmund singular integral operators T with a Lipschitz function b. The corresponding results are also obtained on the commutators Sb generated by b with singular integral operators S with variable kernels.
