摘要

The main result of this paper concerns the mapping properties of fractional geometric maximal functions on ball quasi-Banach function spaces. We obtain it by extending the Rubio de Francia extrapolation theory to the setting of ball quasi-Banach function spaces. As applications, we present the mapping properties of fractional geometric maximal functions on Lorentz spaces and Orlicz-slice spaces.
