Abstract
In this paper, we delve into the cosmological assessments concerning the deceleration parameter [Formula: see text] in the context of the Bianchi type-III cosmological model within the framework of the Saez–Ballester theory of gravitation. By postulating a proportional relationship between the shear scalar ([Formula: see text]) and the expansion scalar ([Formula: see text]), we derive solutions for the corresponding field equations. Additionally, we conduct an examination and evaluation of the model’s physical and kinematic parameters, including the jerk parameter and snap parameter, while also discussing the energy condition of the model. Through the depiction of graphical representations, we illustrate the variations of the cosmological parameters for specific sets of constants.
在本文中，我们深入探讨了在萨兹-巴勒斯特引力理论框架内的比安奇 III 型宇宙学模型中有关减速参数[公式：见正文]的宇宙学评估。通过假设剪切标量（[公式：见正文]）和膨胀标量（[公式：见正文]）之间的比例关系，我们得出了相应场方程的解。此外，我们还检查和评估了模型的物理和运动参数，包括挺举参数和弹跳参数，同时还讨论了模型的能量条件。通过图解，我们说明了特定常数集下宇宙学参数的变化。
