Sažetak

We prove a maximal Fourier restriction theorem for hypersurfaces in ${\mathbb{R}}^d$ for any dimension $d\ge 3$ in a restricted range of exponents given by the Tomas-Stein theorem (spheres being the most canonical example). The proof consists of a simple observation. When $d=3$ the range corresponds exactly to the full Tomas-Stein one, but is otherwise a proper subset when $d>3$. We also present an application regarding the Lebesgue points of functions in $\mathcal{F}(L^p)$ when $p$ is sufficiently close to 1.
