In this article, we examine the solution for expanding cosmology, which imitates properties similar to an interplay of dark matter and dark energy. The effective fluid of this toy model may behaves like dust matter at early epoch and as a cosmological constant at later epoch. Also, for this solution, the cosmological parameters are calculated and the model is able to explain dynamical universe evolution from decelerated to accelerated phase. Further, we investigate the bouncing solution and it’s relation with finite-time singularities in present model with inhomogeneous viscous fluid.

具有非均匀粘性流体的统一和弹跳宇宙学

在本文中，我们研究了扩展宇宙学的解决方案，它模仿了类似于暗物质和暗能量相互作用的特性。该玩具模型的有效流体在早期可能表现为尘埃物质，在后期表现为宇宙常数。此外，对于该解决方案，计算了宇宙学参数，并且该模型能够解释从减速阶段到加速阶段的动态宇宙演化。此外，我们研究了弹跳解及其与现有非均匀粘性流体模型中有限时间奇点的关系。
