A Universal Stein-Tomas Restriction Estimate for Measures in Three Dimensions

  • Alex IosevichEmail author

We study restriction estimates in \({\mathbb{R}}^{3}\) for surfaces given as graphs of low regularity functions. We obtain a “universal” mixed-norm estimate for the extension operator \(f \rightarrow \widehat{ f\mu }\) in \({\mathbb{R}}^{3}\). We also prove that this estimate holds for any Frostman measure supported on a compact set of Hausdorff dimension greater than two. The approach is geometric and is influenced by a connection with the Falconer distance problem.
