论文摘要
我们研究标量场对非线性电动力学空间的影响。使用测试和引力标量场进行研究。在重新访问Einstein-Maxwell标量场解决方案后，我们重点介绍了非线性电动力学标量场空间的分析研究，尤其是方形拉格朗日模型。主要的动机是了解当考虑非线性电动力学作为附加来源时，是否保留了标量场的某些特定特定签名。我们表明，在球形对称的静态标量 - vacuum空间中被标量场破坏的地平线的规律性不会通过包括非线性电动力学或满足某些条件的其他来源来提高。我们使用测试标量字段确认这些发现，使我们能够超越球形对称性。
We study influence of scalar fields on Nonlinear Electrodynamics spacetimes. The investigation is carried out using both test and gravitating scalar fields. After revisiting Einstein-Maxwell scalar field solutions we focus on analytic investigation of Nonlinear Electrodynamics scalar field spacetimes, especially Square Root Lagrangian model. The main motivation being to understand whether certain specific signatures of scalar fields are preserved when Nonlinear Electrodynamics as an additional source is considered. We show that the regularity of horizon which is spoiled by scalar field in spherically symmetric static scalar-vacuum spacetimes is not improved by including Nonlinear Electrodynamics or other sources satisfying certain condition. We confirm these findings using test scalar field that enables us to go beyond spherical symmetry.
