单变量向量场上希尔伯特变换的$L^p$估计

$L^p$ estimates for the Hilbert transforms along a one-variable vector field

Michael Bateman, Christoph Thiele

摘要:

Stein证明了当$v$是Lipschitz时,在向量场方向上的希尔伯特变换有界于$L^2$。当$v$是$\bbr ^2$中的可测、非零、单变量向量场时,我们建立了该算子的广泛的$L^p$估计。除了一个$L^2$估计从一个简单的技巧与Carleson的定理,这些估计是未知的。本文与第一作者最近的一篇论文(\cite{B2})密切相关。

英文摘要:

Stein conjectured that the Hilbert transform in the direction of a vector field is bounded on, say, $L^2$ whenever $v$ is Lipschitz. We establish a wide range of $L^p$ estimates for this operator when $v$ is a measurable, non-vanishing, one-variable vector field in $\bbr ^2$. Aside from an $L^2$ estimate following from a simple trick with Carleson's theorem, these estimates were unknown previously. This paper is closely related to a recent paper of the first author (\cite{B2}).
