论文摘要
无限的建议是一种在半古典引力中提出的宇宙初始条件的理论，并依赖于运动方程的常规（复杂）解决方案的存在。我们通过明确的计算表明，在包含预期的量子重力校正后，常规的无义溶液被修改但未破坏，涉及Riemann Tensor的较高功率以及其协变量的衍生剂。我们用弦理论绘制的示例来说明我们的结果。我们的发现提供了对无限制框架的至关重要的自矛盾测试。
The no-boundary proposal is a theory of the initial conditions of the universe formulated in semi-classical gravity, and relying on the existence of regular (complex) solutions of the equations of motion. We show by explicit computation that regular no-boundary solutions are modified, but not destroyed, upon inclusion of expected quantum gravity corrections that involve higher powers of the Riemann tensor as well as covariant derivatives thereof. We illustrate our results with examples drawn from string theory. Our findings provide a crucial self-consistency test of the no-boundary framework.
