AI中文摘要:
我们认为,通过将路径积分限制为对连通且允许的几何构型求和,可以显著缓解与引力波函数归一化相关的一些令人困惑的特征。该方案应用于经典跃迁时给出了合理的结果,并提供了非平凡的无边界概率,符合早前的预期。我们强调了边界条件和积分轮廓对这些问题的额外影响。
英文摘要:
We argue that some of the puzzling features associated with the normalization of gravitational wave functions can be substantially alleviated by restricting the path integral to a sum over connected, allowable geometries. This prescription gives sensible results when applied to classical transitions and it provides non-trivial no-boundary probabilities, in line with old expectations. We highlight the additional impact of both boundary conditions and integration contours on these issues.
