Vertical versus conical square functions
Pascal Auscher, Steve Hofmann, José Maria Martell
We study the difference between vertical and conical square functions in the abstract and also in the specific case where the square functions come from an elliptic operator.
Sharp weighted estimates for approximating dyadic operators
David Cruz-Uribe, Jose Maria Martell, Carlos Perez
We give a new proof of the sharp weighted inequality ||T||_{L^2(w)} \leq c [w]_{A_2} where is the Hilbert transform, a Riesz transform, the Beurling-Ahlfors operator or a…
Sharp weighted estimates for classical operators
David Cruz-Uribe, Jose Maria Martell, Carlos Perez
We give a new proof of the sharp one weight inequality for any operator that can be approximated by Haar shift operators such as the Hilbert transform, any Riesz transfor…
