哈勃参数与宇宙年龄对爱因斯坦宇宙学方程通解的制约：历史的观点
Constraints on the general solutions of Einstein cosmological equations by Hubble parameter times cosmic age: a historical perspective
摘要：
在历史的角度来看，爱因斯坦方程，包括宇宙学常数和曲率项的紧凑的解决方案，从两个最近的观测估计哈勃的参数（H 0）和宇宙的“年龄”（t0）。在相对较窄的电流不确定度约束下，研究了ΛCDM（Λ冷暗物质）、KOFL（k开Friedman-Lemaitre）以及两个混合解的宇宙学意义. KOFL的定量结果似乎与物质密度和观测到的来自遥远星系的最高红移相一致，而ΛCDM的结果可能更难调和。
英文摘要：
In a historical perspective, compact solutions of Einstein's equations, including the cosmological constant and the curvature terms, are obtained, starting from two recent observational estimates of the Hubble's parameter (H0) and the "age" of the universe (t0). Cosmological implications for ΛCDM (Λ Cold Dark Matter), KOFL (k Open Friedman-Lemaitre), plus two mixed solutions are investigated, under the constraints imposed by the relatively narrow current uncertainties. Quantitative results obtained for the KOFL case seem to be compatible with matter density and the highest observed red-shifts from distant galaxies, while those obtained for the ΛCDM may be more difficult to reconcile.
