三维测度的普适Stein-Tomas限制估计

A universal Stein-Tomas restriction estimate for measures in three dimensions

Alex Iosevich, Svetlana Roudenko

摘要:

本文研究了W^1_1(R^2)(可积梯度)函数图曲面在R^3中的限制估计。我们得到了三维扩张算子f -> \hat{f mu}的“普适”L^2(mu)-> L^4(R^3,L^2(SO(3))估计.我们还证明了三维估计适用于支持在大于2的豪斯多夫维数紧集上的任何Frostman测度。该方法是几何的,并受到连接与法尔科纳距离问题。

英文摘要:

We study restriction estimates in R^3 for surfaces given as graphs of W^1_1(R^2) (integrable gradient) functions. We obtain a "universal" L^2(mu) -> L^4(R^3, L^2(SO(3))) estimate for the extension operator f -> \hat{f mu} in three dimensions. We also prove that the three dimensional 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.
