A1 bounds for Calderón-Zygmund operators related to a problem of Muckenhoupt and Wheeden
Lerner, Andrei K.; Ombrosi, Sheldy J.; Pérez Moreno, Carlos (International Press, 2009)We obtain an Lp(w) bound for Calderón-Zygmund operators T when w ∈ A1. This bound is sharp both with respect to ∥w∥A1 and with respect to p. As a result, we get a new L1,∞(w) estimate for T related to a problem of Muckenhoupt and Wheeden.
