Improved<i>A</i><sub>1</sub>−<i>A</i><sub>∞</sub>and Related Estimates for Commutators of Rough Singular Integrals
Abstract An A 1 − A ∞ estimate, improving on a previous result for [ b, T Ω ] with $\Omega \in L^{infty}({\open S}^{n - 1})$ and b ∈BMO is obtained. A new result in terms of the A ∞ constant and the one supremum A q − A ∞ …
