Open full text 3 citations

Abstract

Lebesgue space estimates are obtained for the circular maximal function on the Heisenberg group H 1 restricted to a class of Heisenberg radial functions.Under this assumption, the problem reduces to studying a maximal operator on the Euclidean plane.This operator has a number of interesting features: it is associated to a non-smooth curve distribution and, furthermore, fails both the usual rotational curvature and cinematic curvature conditions.
