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.

带 SBST 理论中减速参数参数化的比安奇 III 型宇宙学模型研究

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
