论文摘要
在本文中，我们研究了Brans-Dicke（BD）重力理论中Bianchi Type-V宇宙的生存能力。我们已经讨论了BD理论框架内的暗物质（DM）与暗能量（DE）之间的相互作用和非相互作用的情况。 CCA技术已应用于使用46个观察性哈勃数据（OHD），万神殿数据的值（SNIA的最新汇编，in 40 bin in Redshift范围内的$ 0.014 \ leq Z \ leq 1.62 1.62）$及其组合数据集来限制模型参数。我们建立了磁场方程的精确解，以得出派生的宇宙的动力学，并发现获得的结果与观测值一致。我们还指出，减速参数从正向到负面以及存在过渡红移的存在的迹象存在明显的变化。使用各种观察数据点，证明了$（R〜-S）$诊断平面的进化轨迹，以了解Bianchi-V模型的几何行为。还讨论了宇宙的某些物理特性。还值得注意的是，宇宙学参数的结论与现代观察数据一致。
In this paper, we have examined the viability of the Bianchi type-V universe in Brans-Dicke (BD) theory of gravitation. We have discussed the interacting and non-interacting scenarios between dark matter (DM) and dark energy (DE) of the derived universe within the framework of BD theory. CCA technique has been applied to constrain the model parameters using 46 values of observational Hubble data (OHD), Pantheon data (the latest compilation of SNIa with 40 binned in the redshift range $0.014 \leq z \leq 1.62)$ and their combined datasets. We establish an exact solution of the field equations to derive the dynamics of the derived universe and the obtained results are found to agree with the observations. We also noted a distinctive change in the sign of the deceleration parameter from positive to negative, as well as the presence of a transition red-shift exists. Using various observational data points, the evolution trajectories for $(r~- s)$ diagnostic planes are shown to understand the geometrical behavior of the Bianchi-V model. Some physical properties of the universe are also discussed. It's also worth noting that the conclusions of the cosmological parameter are consistent with modern observational data.
