Spherical maximal operators on Heisenberg groups: Restricted dilation sets
Published 4 Aug 2022 in math.CA | (2208.02774v2)
Abstract: Consider spherical means on the Heisenberg group with a codimension two incidence relation, and associated spherical local maximal functions $M_Ef$ where the dilations are restricted to a set $E$. We prove $Lp\to Lq$ estimates for these maximal operators; the results depend on various notions of dimension of $E$.
