从精确的$f(R)$宇宙学模型得到暗能量和尘埃物质相

Dark energy and dust matter phases from an exact $f(R)$-cosmology model

S. Capozziello, P. Martin-Moruno, C. Rubano

摘要:

我们证明了尘埃物质-暗能量组合相可以通过幂律$f(R)$宇宙学模型的精确解得到。这个例子回答了这样一个问题,即在暗能量加速阶段之前,需要一个尘埃主导的减速阶段,以便形成大尺度结构。

英文摘要:

We show that dust matter-dark energy combined phases can be achieved by the exact solution derived from a power law $f(R)$ cosmological model. This example answers the query by which a dust-dominated decelerated phase, before dark-energy accelerated phase, is needed in order to form large scale structures.
