Abstract

In this paper, we introduce a criterion for maximal operators associated with Fourier multipliers to be bounded on L^p(ℝ^d). Noteworthy examples satisfying the criterion are multipliers of the Mikhlin type or limited decay which are not necessarily radial. To do so, we make use of modified square function estimates and bilinear interpolation. In result, we obtain convergence results for fractional half-wave equations and surface averages as well as the L^p boundedness for the maximal operators.
