Abstract

We prove that if f:I⊂ R R is of bounded variation, then the noncentered maximal function Mf is absolutely continuous, and its derivative satisfies the sharp inequality \|DMf\|1 |Df|(I). This allows us obtain, under less regularity, versions of classical inequalities involving derivatives.
