Abstract

We study Lp boundedness of the maximal average over dilations of a smooth hypersurface S. When the decay rate of the Fourier transform of a measure on S is 1/2, we establish the optimal maximal bound, which settles the conjecture raised by Stein. Additionally, when S is not flat, we verify that the maximal average is bounded on Lp for some finite p, which generalizes the result by Sogge and Stein.
