Sharp weighted weak-type bounds for commutators of singular integrals

Adam Mair, Óscar Andrés Ramírez, Cody B. Stockdale

We establish sharp weak-type bounds for commutators of Calderón--Zygmund operators and $\text{BMO}({\mathbb{R}}^n)$ symbols with respect to $A_p$ weights. We prove that the bound \lo…
