We prove Lpestimates for oscillating spectral multipliers on Lie groups of polynomial volume growth and Riemannian manifolds of nonnegative curvature. We apply these results to obtain Lpestimates for the Riesz means of the Schrodinger operator. © 1994, Mathematical Institute, Tohoku University. All rights reserved.
