In this thesis, we study the necessary and sufficient conditions for the L^p-boundedness of the commutators related to Calderón-Zygmund operators. Let K be Calderón-Zygmund operators, if b is a BMO function, then the upper bound of commutators [b,K] is controlled by BMO norm of b. Conversely, if we only consider Riesz tranform R_j, then the lower bound of commutators [b,R_j] is also controlled by BMO norm of b. We mainly sort out the proof method published by Coifman, Rochbe and Weiss in Annals Math (Factorization theorems for Hardy spaces inseveral variables), and describes in detail so that readers can understand by the knowledge of real analysis. At the end, we provide another way to prove the condition of lower bound. |
