AbstractLet
$$mathbb{I}^n = mathbb{C}^n imes mathbb{R}$$
be the Heisenberg group and μr be the normalized surface measure on the sphere of radiusr in ℂn. Let
$$Mf = sup _{r > 0} left| {f * mu _r }
ight|$$
. We prove an optimalLp-boundedness result for the spherical maximal functionMf, namely we prove thatM is bounded onLp(In) if and only ifp>2n/2n−1.
