论文摘要
我们使用Wald-Jacobson-Myers熵而不是Bekenstein-Hawking熵提出了超出一般相对性（GR）的重力理论（GR）的协变熵。我们首先扩展了在4维GR中已知的结合的证明，到D维GR，F（r）重力和规范标量调整理论。然后，我们将Einstein-Gauss-Bonnet（EGB）重力视为一个更加平底的例子，在一组合理的假设下，证明了球形对称构型的GR分支中的结合。作为推论，表明在无效的能量条件下，广义的第二定律在完全非线性水平的EGB重力的球形对称构型的GR分支中。
We propose a covariant entropy bound in gravitational theories beyond general relativity (GR), using Wald-Jacobson-Myers entropy instead of Bekenstein-Hawking entropy. We first extend the proof of the bound known in 4-dimensional GR to D-dimensional GR, f(R) gravity and canonical scalar-tensor theory. We then consider Einstein-Gauss-Bonnet (EGB) gravity as a more non-trivial example and, under a set of reasonable assumptions, prove the bound in the GR branch of spherically symmetric configurations. As a corollary, it is shown that under the null and dominant energy conditions, the generalized second law holds in the GR branch of spherically symmetric configurations of EGB gravity at the fully nonlinear level.
