Abstract

We construct cosmological models for dark energy based on Lyra’s geometry for the Bianchi-I space-time to understand the evolution of the universe. The specific choice of the deceleration parameter \(q=-\frac{\alpha _1}{t^2}+\alpha _2-1\) is used to determine the exact solutions of the field equations in Lyra geometry. The parameter \(\alpha _1\) has a dimension equal to the square of time. Further, we have discussed two cosmological models depending on the parameter \(\alpha _2\). Several physical parameters are obtained and the results in both the models are analyzed and presented graphically for the analysis of the results.

天琴座几何中的暗能量宇宙学模型
我们根据天琴座的比安奇时空几何构造暗能量的宇宙学模型,以了解宇宙的演化。减速参数\(q=-\frac{\alpha _1}{t^2}+\alpha _2-1\)的具体选择用于确定Lyra几何中场方程的精确解。参数\(\alpha _1\)的维度等于时间的平方。此外,我们还讨论了依赖于参数\(\alpha _2\)的两种宇宙学模型。得到了几个物理参数,并对两种模型的结果进行了分析,并以图形形式给出了分析结果。
