标题： Dependence of Inflationary Reconstruction upon Cosmological Parameters

摘要： 膨胀势及其导数决定了在膨胀期间量子涨落产生的标量和张量度规扰动的谱。 CBR各向异性提供了一种有前途的方法来确定度规扰动的谱，从而为约束膨胀势提供了方法。 度规扰动与CBR各向异性的关系取决于宇宙学参数——尤其是宇宙常数的可能性。 鉴于一些关于宇宙常数的观测证据（大尺度结构、星系团-重子比例、哈勃常数和宇宙年龄的测量），我们推导了在存在宇宙常数的情况下二阶的重建方程和一致性关系。 我们还澄清了之前的符号，并讨论了重建的其他方案。 显示英文摘要

摘要： The inflationary potential and its derivatives determine the spectrum of scalar and tensor metric perturbations that arise from quantum fluctuations during inflation. The CBR anisotropy offers a promising means of determining the spectra of metric perturbations and thereby a means of constraining the inflationary potential. The relation between the metric perturbations and CBR anisotropy depends upon cosmological parameters -- most notably the possibility of a cosmological constant. Motivated by some observational evidence for a cosmological constant (large-scale structure, cluster-baryon fraction, measurements of the Hubble constant and age of the Universe) we derive the reconstruction equations and consistency relation to second order in the presence of a cosmological constant. We also clarify previous notation and discuss alternative schemes for reconstruction.
