Spherical maximal estimates via geometry

Classical Analysis and ODEs 2024-12-19 v1

Abstract

We present a simple geometric approach to studying the LpL^p boundedness properties of Stein's spherical maximal operator, which does not rely on the Fourier transform. Using this, we recover a weak form of Stein's spherical maximal theorem.
