摘要

我们分析了平坦的弗里德曼-勒梅特-罗伯逊-沃克宇宙学的球形扰动中质量密度对比的演变。暗物质和暗能量都包含在内。在没有暗能量的情况下，演化方程与波诺在 "牛顿宇宙学 "中得到的方程相吻合。

The Mass Density Contrast in Perturbed Friedman–Lemaître–Robertson–Walker Cosmologies
We analyze the evolution of the mass density contrast in spherical perturbations of flat Friedman-Lemaitre-Robertson-Walker cosmologies. Both dark matter and dark energy are included. In the absence of dark energy the evolution equation coincides with that obtained by Bonnor within the ``Newtonian cosmology''.
