标题： Effects of Charge and Gravitational Decoupling on Complexity and Isotropization of Anisotropic Models

摘要： 本文通过采用最小几何变形，在爱因斯坦-麦克斯韦框架下构建了现有各向异性解的两个直接扩展。 为了实现这一点，我们假设一个最初充满各向异性流体的静态球形内部，并将其称为种子源。 我们通过包括一个新的源来扩展这种物质配置，该源对自引力系统的影响由一个解耦参数控制。 类似于总流体源的带电场方程被制定出来。 然后，我们对径向度规势实施一个变换，将场方程分成两个新的欠定系统，分别对应初始源和新源。 其中第一个通过采用两个已知的度规假设来解决，以便处理未知数的数量。 此外，利用总各向异性为零和无复杂性约束来求解第二个系统。 估计的紧凑星体$4U~1820-30$的半径和质量被用于以图形方式解释不同电荷和解耦参数$\omega$值的结果解。 我们得出结论，我们的两个模型在除$\omega=1$以外的所有参数值下都是物理上可接受的。 显示英文摘要

摘要： This paper constructs two immediate extensions of the existing anisotropic solutions in the context of Einstein-Maxwell framework by employing minimal geometric deformation. To achieve this, we assume a static spherical interior initially filled with anisotropic fluid and call it a seed source. We extend this matter configuration by including a new source whose impact on the self-gravitating system is governed by a decoupling parameter. The charged field equations analogous to the total fluid source are formulated. We then implement a transformation on the radial metric potential that divides the field equations into two new under-determined systems, corresponding to the initial and new sources. The first of them is addressed by taking two well-known metric ansatz so that the number of unknowns can be tackled. Further, the vanishing of total anisotropy and complexity-free constraints are used to solve the second set. The estimated radius and mass of a compact star $4U~1820-30$ is utilized to interpret the resulting solutions graphically for different values of the charge and decoupling parameter $\omega$. We conclude that our both developed models are physically acceptable for all parametric values except $\omega=1$.
