WebThe spherical maximal function sd satisfies an Lp (Nv)-inequality where 2h/(2h — 1) < ρ < oo and h is the largest integer such that h < v(v — l)/4 — 1. This result is new, but probably not sharp for the range of p. The group Nv does not fulfill the non-degeneracy condition of [9], and the surface is not of the type studied there neither. Webthe spherical maximal function on the Heisenberg group Hn, for n 2. By suitable adaptation of an approach developed by M. Lacey in the Euclidean case, we obtain sparse bounds for these maximal functions, which lead to new unweighted and weighted estimates.
