A conjecture for arithmetic spherical maximal functions

Classical Analysis and ODEs 2026-05-22 v1

Abstract

For 24 years, it has been an open problem to obtain improved bounds, for the maximal function over a sparse sequence of discrete spherical averages, going beyond the range for the full discrete spherical maximal function. I formulate a conjecture to characterize the boundedness of such maximal functions and state a theorem in support of it.
