标题： The Impact of Quantum Cosmology on Quantum Field Theory

摘要： 量子宇宙学的基本问题是定义宇宙的量子态，并在黎曼三几何上设定适当的边界条件。 本文描述了在欧几里得麦克斯韦理论和线性化引力的量子振幅相应分析中的最新进展。 在法迭夫-波波夫形式框架和ζ函数正则化下，各种混合边界条件的选择有助于更深入地理解边界存在时的量子规范场和量子引力。 显示英文摘要

摘要： The basic problem of quantum cosmology is the definition of the quantum state of the universe, with appropriate boundary conditions on Riemannian three-geometries. This paper describes recent progress in the corresponding analysis of quantum amplitudes for Euclidean Maxwell theory and linearized gravity. Within the framework of Faddeev-Popov formalism and zeta-function regularization, various choices of mixed boundary conditions lead to a deeper understanding of quantized gauge fields and quantum gravity in the presence of boundaries.
