f(R)引力的Cauchy问题

The Cauchy problem of f(R) gravity

Nicolas Lanahan-Tremblay, Valerio Faraoni

摘要:

利用度规引力和Palatini引力与Brans-Dicke引力的动力学等价性,研究了它们的初值问题.柯西问题在有物质存在的情况下是度量f(R)引力的良好形式,在真空中是适定的。相反,对于Palatini f(R)引力,柯西问题没有很好的公式化。

英文摘要:

The initial value problem of metric and Palatini f(R)gravity is studied by using the dynamical equivalence between these theories and Brans-Dicke gravity. The Cauchy problem is well-formulated for metric f(R)gravity in the presence of matter and well-posed in vacuo. For Palatini f(R)gravity, instead, the Cauchy problem is not well-formulated.
