This work employs the minimal geometric deformation decoupling scheme to derive interior stellar solutions in the background of an electrically charged BTZ ansatz as a seed metric in three dimensions. In this respect, we impose two different equations of state to determine the deformation function and the new material contributions emerging from the additional field source. Furthermore, we describe the finiteness of all thermodynamic quantities of the presented stellar solutions, including the effective thermodynamical quantities, for varying values of the deformation parameter and total electric charge. We explore the new interior astrophysical solutions in three-dimensional gravity by analyzing the charged BTZ metric, admitting circular symmetry through the principles of geometric deformation. This study examines the impact of radial-metric deformation on the charged BTZ geometry and underscores the importance of stellar decoupling within the context of electrically charged dense distributions. It is shown that new physically acceptable solutions by incorporating any known three-dimensional spacetime as the isotropic basis are possible, which in turn enable one to analyze the quantum effects due to low degrees of freedom at lower dimensions.

本论文致力于研究黑洞的几何性质和弦论中的可积结构。在第一部分中，我们将研究视界的对称性及其体延拓。通过考虑扰动理论中杂化超引力的α'修正，研究了超引力近似下的视界猜想，并指出标准的整体方法不再适用.一个充分条件，建立视界猜想将被确定。作为我们的分析的结果，我们发现了一个不去定理AdS 2背景的杂种优势理论。然后，将在各种理论中考虑规定的近地平线几何的整体扩展。视界场在径向坐标系中作一阶展开。通过证明径向变形的模空间必须满足椭圆偏微分方程，证明了径向变形的模空间是有限维的。在第二部分中，将讨论可积反德西特背景的几何方面和光谱性质。我们在AdS 2 x S2 x T6 IIB超弦中构造了一个Bethe算符，克服了缺乏伪真空态对本底的影响.在AdS 3 x S3 x T4 IIB超弦中，我们证明了q-变形Poincaré超代数的boost生成元湮灭了S-矩阵，并将此条件解释为S-矩阵关于纤维丛上联络的平行方程.这暗示着与散射过程相关的代数问题可以用几何方法重写。这使我们能够提出一个通用的S矩阵。
