本文讨论了各向异性荷电圆柱几何体的稳定性分析与修正引力理论的耦合问题。在这里，拉格朗日量是里奇迹和应力张量的变化函数。为了考察各向异性圆柱形宇宙天体在电磁作用下的稳定行为，我们计算了修正的运动方程和连续性方程。在理论的背景下。利用微扰技术，我们建立了一个修正的坍缩方程（），它包含了带电情形下的几何和物理变量。我们的研究继续下的非最小耦合功能。此外，我们还利用流体的刚性参数（），通过对物理参数施加一些约束，研究了荷电几何在牛顿和后牛顿（）时代的动力学稳定相。
This paper deals with stability analysis of anisotropic-charged cylindrical geometry coupled withmodified gravity theory (). In this, the Lagrangian is a varying function of traces of Ricci and stress tensors. In order to examine the stable behavior of the anisotropic cylindrical cosmic object under the electromagnetic effects, we calculated the modified equations of motion and equations of continuity. in the background oftheory. By utilizing the perturbation technique, we constitute a modified collapse equation (), which contains geometrical and physical variables in the charged scenario. Our investigation continues under the nonminimally coupled function of. Furthermore, we investigate the dynamically stable phases of charged geometry at Newtonianand post-Newtonian () epochs with the help of the rigidity parameter of fluid () by imposing some constraints on physical parameters.
