Abstract

We prove a weighted norm inequality for the maximal Bochner--Riesz operator and the associated square-function. This yields new Lp(Rd)L^p(R^d) bounds on classes of radial Fourier multipliers for p2+4/dp\ge 2+4/d with d2d\ge 2, as well as space-time regularity results for the wave and Schr\"odinger equations.
