振荡FRW宇宙学中的特殊耦合暗能量
Specially Coupled Dark Energy in the Oscillating FRW Cosmology
摘要:
我们考虑一个四维平坦空间的Friedman宇宙,其中充满了两种相互作用的理想流体(暗能量与特殊形式的暗物质的耦合)。解出了引力运动方程。结果表明,在某些情况下,存在一个具有有限时间宇宙学奇点的周期宇宙,并且宇宙在遥远的未来是静态的。
英文摘要:
We consider a four-dimensional flat-space Friedman universe, which is filled with two interacting ideal fluids (the coupling of dark energy with dark matter of special form). The gravitational equations of motion are solved. It is shown that in some cases there appears a periodic universe with finite-time cosmological singularities and also the universe becomes static in the remote future.
