论文摘要
解决了Braneworld宇宙学在五维的爱因斯坦 - 加斯 - 邦纳特重力中的热力学稳定性，尤其是在分裂真空薄壳的背景下，壳代表短暂的短暂或分支变换的虚假真空吸尘器自发地分配的溶液和一个可能的数据集。计算与竞争解决方案相关的自由能。结果表明，确定哪种解决方案的标准与具有分裂溶液的可能性的标准相吻合。该结果表明，在可能的经典解决方案中，热力学和动态选择标准之间具有等效性，应进一步考虑。
The thermodynamic stability of braneworld cosmological solutions in five-dimensional Einstein-Gauss-Bonnet gravity is addressed, particularly in the context of the splitting vacuum thin shells in which the shells represent either an ephemeral or a branch-changing false vacuum bubble spontaneously emerging from the braneworld and there is more than one possible solution for the same distributional initial data set. The free energy associated with the competing solutions is computed. It is shown that the criterion to decide which solution is preferred coincides with the criterion of the possibility of having a splitting solution. This result suggests an equivalence between a thermodynamic and a dynamic selection criteria among possible classical solutions that deserve further consideration.
