摘要:

本文研究了在标量场存在下Rastall理论静态球对称解在球对称扰动下的稳定性。结果表明,稳定性分析是不一致的,在这个意义上,线性时间依赖扰动不存在,我们可以得出结论,这些解决方案是稳定的。这种不一致的可能原因进行了讨论。

英文摘要:

We study the stability of static, spherically symmetric solutions of Rastall's theory in the presence of a scalar field with respect to spherically symmetric perturbations. It is shown that the stability analysis is inconsistent in the sense that linear time-dependent perturbations cannot exist, and we can conclude that these solutions are stable. Possible reasons for this inconsistency are discussed.
