Our main theorem extends the key result from D. Cruz-Uribe, J.M. Martell and C. Pérez, Weighted weak-type inequalities and a conjecture of Sawyer, Int. Math. Res. Not., 30 2005, 1849-1871.engjournal article1730-6302https://doi.org/10.4064/cm4939-6-2016open accessMaximal functionsMixed weak-type inequalitiesSingular integral operatorsWeightsAnálisis matemático12 Matemáticas
