Anti-de Sitter体中De Sitter膜附近的Klein-Gordon方程

On the Klein-Gordon equation near a De Sitter brane in an Anti-de Sitter bulk

Alain Bachelot

摘要:

本文研究了嵌入Anti-de Sitter体中的De Sitter膜的过去因果域上的Klein-Gordon方程。我们解决了全局混合双曲问题。我们证明,任何有限能量的解决方案可以表示为一个卡鲁扎-克莱因塔,这是一个叠加的自由场在稳态宇宙中,我们研究的渐近行为。我们证明了引力涨落的主导项是无质量引力子,即De Sitter膜是线性稳定的。

英文摘要:

In this paper we investigate the Klein-Gordon equation in the past causal domain of a De Sitter brane imbedded in a Anti-de Sitter bulk. We solve the global mixed hyperbolic problem. We prove that any finite energy solution can be expressed as a Kaluza-Klein tower that is a superposition of free fields in the Steady State Universe, of which we study the asymptotic behaviours. We show that the leading term of a gravitational fluctuation is a massless graviton, i.e. the De Sitter brane is linearly stable.
