关于非最小耦合$f(R)$理论可行性的注记
A note on viability of nonminimally coupled $f(R)$ theory
摘要:
非最小耦合$f(R)$理论的一致性条件已通过要求快子和标量涨落中的不稳定性的情况下导出。本说明证实了这些结果,并澄清了关于声速的不同定义的微妙之处。
英文摘要:
Consistency conditions for nonminimally coupled $f(R)$ theories have been derived by requiring the absence of tachyons and instabilities in the scalar fluctuations. This note confirms these results and clarifies a subtlety regarding different definitions of sound speeds.
