摘要

本文揭示了静态球面分布中的复杂性概念,并在带电 f(R) 框架内对其进行了扩展探索。为此,我们首先提出了描述各向异性内部的修正爱因斯坦-麦克斯韦场方程。通过正交分割曲率张量,出现了一系列特定的标量,其中最突出的是 YTF,它被称为当前流体分布中的复杂性因子。在处理具有额外自由度的场方程时,我们引入了复杂性消失条件。该条件与三个额外的约束条件相结合,为开发不同的模型铺平了道路。对于所选参数值,我们还以图解的方式说明了所得到的解决方案。通过分析,我们得出了一个令人信服的结论:所有三个模型都满足特定参数值下物理相关结构存在的必要条件。

Charged anisotropic Starobinsky models admitting vanishing complexity

Unveiling the notion of complexity within the static spherical distribution, this paper extends its exploration in the charged f(R) framework. For this, we start with the formulation of the modified Einstein–Maxwell field equations, describing the anisotropic interior. By orthogonally splitting the curvature tensor, a collection of specific scalars emerges, with one standout, YTF, titled as the complexity factor in the current fluid distribution. Tackling the field equations with additional degrees of freedom, we introduce the vanishing complexity condition. This condition, combined with three additional constraints, paves the way for the development of different models. The resulting solutions are also illustrated graphically for chosen parametric values. Through this analysis, we draw the compelling conclusion that all three models fulfill the essential criteria necessary for physically relevant structures to exist for specific parametric values.
