Abstract
The theory of Muckenhoupt weights allows us to characterize when Calderón-Zygmund operators are bounded on weighted Lp spaces. A consequence of that theory is the celebrated Coifman-Rochberg-Weiss Commutator Theorem, which states that the commutator between a BMO function and a Calderón-Zygmund operator is always bounded on Lp (p strictly greater than 1 and finite). The objective of this …
