In the present paper, we analyze the well-known 2+1 dimensional black holes (assuming a non-vanishing cosmological constant) in light of the gravitational decoupling by the minimal geometric deformation approach. To illustrate our results, we consider the BTZ geometry as the seed solution to generate new anisotropic ones. To complement the study, the curvature scalars and the energy conditions are analyzed.

重力解耦的各向异性2 + 1维黑洞

在本文中，我们通过最小几何变形方法根据重力解耦分析了著名的2 + 1维黑洞（假设宇宙学常数不变）。为了说明我们的结果，我们将BTZ几何形状视为生成新各向异性的种子解决方案。为了补充研究，分析了曲率标量和能量条件。
