论文摘要
对量子宇宙学的路径积分方法的回顾及其与规范定量的关系。讨论了使用Picard-Lefshets理论的欧几里得爱因斯坦 - 希尔伯特动作中的hartle-hawking和vilenkin波函数的初始推导。然后采用爱因斯坦 - 卡丹作用的路径积分定量，以获取由物质和辐射主导的MinisuperSpace封闭的FRW宇宙的波形。这些计算与Magueijo最近使用同一动作的规范定量进行的计算相称。
A review of the path integral approach to quantum cosmology and its relation to canonical quantisation. The initial derivation of the Hartle-Hawking and Vilenkin wavefunctions from the Euclidean Einstein-Hilbert action, and later, from the Lorentzian path integral using Picard-Lefshets Theory is discussed. Path integral quantisation of the Einstein-Cartan action is then employed to obtain the wavefunctions for minisuperspace closed FRW universes dominated by matter and radiation. These calculations are complimentary to those recently carried out by Magueijo using canonical quantisation of the same action.
