Abstract

In this paper, we have put forwarded a detailed investigation on the cosmic evolution of Bianchi type III model within the realm of Born-Infeld f(R) gravity executing the Palatini approach. Using a very eminent tool known as Dynamical System Approach (DSA), we have curtailed the complexity of the non linear field equations and study the dynamics for the form \(f(R) =R-\beta / R^n\). The main focus of our work is to retrieve the sequence of cosmic evolution and to study the evolution of shear as well as spatial curvature.

Born-Infeld f(R)引力理论下Bianchi III模型的宇宙演化

在本文中，我们采用帕拉蒂尼方法，在玻恩-因费尔德f(R)引力领域内对比安奇III型模型的宇宙演化进行了详细研究。我们使用了一个非常著名的工具--动力学系统方法（DSA）--降低了非线性场方程的复杂性，并研究了形式为 \(f(R) =R-\beta / R^n\) 的动力学。我们工作的重点是检索宇宙演化序列，研究剪切力和空间曲率的演化。
