Corrigendum to “Improvements on Sawyer‐type estimates for generalized maximal functions”

Abstract

AbstractThe purpose of this note is to correct a mixed estimate involving the generalized maximal function , when Φ is a Young function satisfying certain properties. The family considered include type functions. Although the obtained estimates turn out to be slightly different, they are still good extensions of mixed inequalities for the classical Hardy–Littlewood maximal operators corresponding to the power functions , with . They also allow us to derive the boundedness properties of between Lebesgue spaces by using interpolation techniques related to endpoint estimates of modular type.
