标题： Nonlinear electrodynamics in 3D gravity with torsion

摘要： 我们研究了非线性电动力学与具有扭力的三维引力之间的精确解。 我们证明，在任何静态且球对称的配置中，电磁场至少有一个分量必须为零。 在理论的电荷区域中，我们构造了一个精确解，其特征是周向电场。 当电磁作用被拓扑质量项修改时，我们找到了两种类型的自对偶解。 显示英文摘要

摘要： We study exact solutions of nonlinear electrodynamics coupled to three-dimensional gravity with torsion. We show that in any static and spherically symmetric configuration, at least one component of the electromagnetic field has to vanish. In the electric sector of the theory, we construct an exact solution, characterized by the azimuthal electric field. When the electromagnetic action is modified by a topological mass term, we find two types of the self-dual solutions.
