Horndeski理论对全球解决方案的挑战

Challenges to global solutions in Horndeski's theory

Laura Bernard, Luis Lehner, Raimon Luna

摘要:

我们探讨的问题,获得全球解决方案Horndeski的引力理论。为此,我们研究了相关的一套理论,并通过采用爱因斯坦框架,我们简化了分析,利用已知的结果波动方程的全局解。我们确定了实现全球解决方案的条件以及可能出现的破坏这一目标的障碍。我们通过数值模拟来说明这些问题。

英文摘要:

We explore the question of obtaining global solutions in Horndeski's theories of gravity. Towards this end, we study a relevant set of the theory and, by employing the Einstein frame we simplify the analysis by exploiting known results on global solutions of wave equations. We identify conditions for achieving global solutions as well as obstacles that can arise to spoil such goal. We illustrate such problems via numerical simulations.
