Extensions of Rubio de Francia's extrapolation theorem
Cruz Uribe, David; Martell Berrocal, José María; Pérez Moreno, Carlos (Universitat de Barcelona, 2006)One of the main results in modern harmonic analysis is the extrapolation theorem of J.L. Rubio de Francia for Ap weights. ...

Extrapolation from A∞ weights and applications
Cruz Uribe, David; Martell Berrocal, José María; Pérez Moreno, Carlos (Elsevier, 2004-08-15)We generalize the Ap extrapolation theorem of Rubio de Francia to A∞ weights in the context of Muckenhoupt bases. Our ...

Sharp two-weight inequalities for singular integrals, with applications to the Hilbert transform and the Sarason conjecture
Cruz Uribe, David; Martell Berrocal, José María; Pérez Moreno, Carlos (Elsevier, 2007-12-20)We prove two-weight norm inequalities for Calderón-Zygmund singular integrals that are sharp for the Hilbert transform ...

Sharp weighted estimates for approximating dyadic operators
Cruz Uribe, David; Martell Berrocal, José María; Pérez Moreno, Carlos (American Mathematical Society, 2010)We give a new proof of the sharp weighted L2 inequality ||T||_{L^2(w)} \leq c [w]_{A_2} where T is the Hilbert transform, ...

Sharp weighted estimates for classical operators
Cruz Uribe, David; Martell Berrocal, José María; Pérez Moreno, Carlos (Elsevier, 2012-01-15)We prove sharp one and two-weight norm inequalities for some of the classical operators of harmonic analysis: the Hilbert ...

The boundedness of classical operators on variable L-p spaces
Pérez Moreno, Carlos; Cruz Uribe, David; Fiorenza, Alberto; Martell Berrocal, José María (2006) -

Two weight extrapolation via the maximal operator
Cruz Uribe, David; Pérez Moreno, Carlos (Elsevier, 2000-06-20)We give several extrapolation theorems for pairs of weights of the form (w, Mkw) and (w, (Mw/w)r w), where w is any ...

Two-weight, weak-type norm inequalities for fractional integrals, Calderón-Zygmund operators and commutators
Cruz Uribe, David; Pérez Moreno, Carlos (Indiana University, 2000)We give Ap-type conditions which are sufficient for the two-weight, weak-type (p, p) inequalities for fractional integral ...

Two-weight, weak-type norm inequalities for singular integral operators
Cruz Uribe, David; Pérez Moreno, Carlos (International Press, 1999)We give a sufficient condition for singular integral operators and, more generally, Calder´on-Zygmund operators to satisfy ...
