Derivative bounds for fractional maximal functions

arXiv:1510.02965 · doi:10.1090/tran/6844

Abstract

In this paper we study the regularity properties of fractional maximal operators acting on -functions. We establish new bounds for the derivative of the fractional maximal function, both in the continuous and in the discrete settings.
