wave equation双线性估计的物理空间方法

A physical space approach to wave equation bilinear estimates

Sergiu Klainerman, Igor Rodnianski, Terence Tao

摘要:

Minkowski空间中波动方程的双线性估计通常使用傅里叶变换和Plancherel定理来证明。然而,这样的方法很难推广到非平坦的情况(例如具有粗糙度量的波动方程,或者具有非零曲率的连接)。在这份说明中,我们给出了一些技术来证明这些估计依赖于物理空间的方法,如向量场,管本地化,分裂成粗,细尺度,归纳尺度(在最近的精神沃尔夫论文)。

英文摘要:

Bilinear estimates for the wave equation in Minkowski space are normally proven using the Fourier transform and Plancherel's theorem. However, such methods are difficult to carry over to non-flat situations (such as wave equations with rough metrics, or with connections with non-zero curvature). In this note we give some techniques to prove these estimates which rely more on physical space methods such as vector fields, tube localization, splitting into coarse and fine scales, and induction on scales (in the spirit of recent papers of Wolff).
