Abstract

Considering the interaction among matter, vacuum, and radiation, this paper investigates the evolution of cosmic dynamics of the varying-vacuum model in a case of Finslerian geometry through dynamic analysis methods. Surprisingly, this model can alleviate the coincidence problem and allows for a stable later cosmological solution corresponding to the accelerating universe.

具有三重相互作用流体的变真空芬斯勒-兰德斯宇宙学中的非线性动力学

考虑到物质、真空和辐射之间的相互作用，本文通过动态分析方法研究了芬斯勒几何情况下变化真空模型的宇宙动力学演化。令人惊奇的是，该模型可以缓解重合问题，并可以得到与加速宇宙相对应的稳定的后期宇宙学解。
