Abstract
Consider R d x R m with the group structure of a twostep nilpotent Lie group and natural parabolic dilations. The maximal function originally introduced by Nevo and Thangavelu in the setting of the Heisenberg group deals with noncommutative convolutions associated to measures on spheres or generalized spheres in R d . We drop the nondegeneracy assumptions in the known results on M & eacute;tivier groups and prove the sharp L p boundedness result for all two step nilpotent Lie groups with d >= 3.
