摘要

本文研究了广义finsler - randes时空中具有宇宙学常数\(\Lambda \)的Finsler-Modified randes宇宙学模型（FMRCM），探讨了该模型在不同能量条件下的解。此外，我们还分析了宇宙常数\(\Lambda \)在各种情况下的作用，探讨了它对宇宙膨胀加速和减速阶段的影响。

Finsler–modified Randers cosmological models in Einstein field theory

In this research article, we have considered the Finsler–Modified Randers Cosmological model (FMRCM) with Cosmological constant \(\Lambda \) for generalized Finsler–Randers space time, to investigate the solutions of this model in Einstein theory of cosmology in different variations of energy conditions. Also, we have analyzed the role of cosmological constant \(\Lambda \) in various scenarios, exploring its impact on both accelerating and decelerating phases of cosmic expansion.
