标题： Loop quantum cosmology: relation between theory and observations

摘要： 本章回顾了在圈量子宇宙学中为宇宙扰动理论开发的框架，并讨论了其在早期宇宙各种模型中的应用，包括暴胀、循环和物质反弹，重点在于潜在的观测后果。 它还讨论了包括非高斯性和背景各向异性在内的扩展，以及关于超普朗克扰动和量化歧义性的局限性。 最后总结了近期研究圈量子宇宙学与完整圈量子引力之间关系的工作。 显示英文摘要

摘要： This chapter provides a review of the frameworks developed for cosmological perturbation theory in loop quantum cosmology, and applications to various models of the early universe including inflation, ekpyrosis and the matter bounce, with an emphasis on potential observational consequences. It also includes a discussion on extensions to include non-Gaussianities and background anisotropies, as well as on its limitations concerning trans-Planckian perturbations and quantization ambiguities. It concludes with a summary of recent work studying the relation between loop quantum cosmology and full loop quantum gravity.
