高维引力波的特征

Features of gravitational waves in higher dimensions

Otakar Svitek

摘要:

四维和更高维的引力波,即所谓的膜世界结构,有几个根本的区别。其中之一是它们在柯西问题中的渐近行为。本研究与所谓的阿达玛问题有关,阿达玛问题是针对惠更斯原理的有效性问题。我们研究了膜世界场景对FRW背景下引力波传播特性的影响。

英文摘要:

There are several fundamental differences between four-dimensional and higher-dimensional gravitational waves, namely in the so called braneworld set-up. One of them is their asymptotic behavior within the Cauchy problem. This study is connected with the so called Hadamard problem, which aims at the question of Huygens principle validity. We investigate the effect of braneworld scenarios on the character of propagation of gravitational waves on FRW background.
