论文摘要

在本研究中,我们研究了暗能量与暗物质之间的相互作用,尤其是强调了曲率在弗里德曼·莱米特雷·罗伯逊 - 沃克(FLRW)时空中曲率的影响。我们通过形成各种临界点的动态方程组来检查系统。后来,我们研究了它们的稳定性特征,并表明,通过适当的潜力选择,该系统在不断扩展的环境中产生了延迟的吸引子(稳定)解决方案。最后,我们使用相空间肖像工具介绍了模型的宇宙学兼容性。

In the present study, we investigate the interaction between dark energy and dark matter, particularly emphasizing the effects of curvature in the realm of Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time. We examine the system by forming a dynamic set of equations for various critical points. Later, we study their stability characteristics and show that with a suitable choice of potential, the system gives rise to the late-time attractor (stable) solution in the expanding environment. Lastly, we present the cosmological compatibility of the model using the phase-space portrait tools.
