渐近平坦流形上的Reynsey猜想

The Glassey conjecture on asymptotically flat manifolds

Chengbo Wang

摘要:

我们在渐近平坦流形$(R^{1+3}, g)$上证明了3-维Brachsey猜想,其中度量$g$是平坦度量的某个时空小扰动,以及非陷获的渐近欧氏流形.此外,对于具有$n\ge 3$的径向渐近平坦流形$(R^{1+n}, g)$,我们在径向情形下验证了Alfressey猜想.讨论了具有较高正则性的高维波动方程。其主要思想是利用当地的能量和KSS估计与变系数,连同加权Sobolev估计,包括跟踪估计。

英文摘要:

We verify the 3-dimensional Glassey conjecture on asymptotically flat manifolds $(R^{1+3}, g)$, where the metric $g$ is certain small space-time perturbation of the flat metric, as well as the nontrapping asymptotically Euclidean manifolds. Moreover, for radial asymptotically flat manifolds $(R^{1+n}, g)$ with $n\ge 3$, we verify the Glassey conjecture in the radial case. High dimensional wave equations with higher regularity are also discussed. The main idea is to exploit local energy and KSS estimates with variable coefficients, together with the weighted Sobolev estimates including trace estimates.
