RT Journal Article T1 Calderón-Zygmund operators and commutators on weighted Lorentz spaces A1 Soria de Diego, Francisco Javier A1 Carro Rossell, María Jesús A1 Li, Hongliang A1 Sun, Qinxiu AB We find necessary conditions (which are also sufficient, for some particular cases) for a pair of weights u and w such that a Calder_on-Zygmund operator T, or its commutator [b; T], with b 2 BMO, is bounded on the weighted Lorentz spaces _p u(w), for 1 < p < 1. This result completes the study already known for the Hardy-Littlewood maximal operator and the Hilbert transform, and hence unifies the weighted theories for the Ap and Bp classes.
