论文摘要
最近引入了非线性麦克斯韦·拉格朗日（Nonlinear），既保存保形，又保存（2）二元性旋转不变性。在这里，在爱因斯坦的重力理论与这种非线性电动力学的最低限度相结合的情况下，我们获得了一个黑洞解决方案，该解决方案是Reissner-Nordström黑洞，其中一个来自非线性理论的附加参数。我们采用因果关系和单位性原则来确定该自由参数的上限。研究了该参数对黑洞溶液物理特性的影响。
The nonlinear Maxwell Lagrangian preserving both conformal and SO(2) duality-rotation invariance has been introduced very recently. Here, in the context of Einstein's theory of gravity minimally coupled with this nonlinear electrodynamics, we obtain a black hole solution which is the Reissner-Nordström black hole with one additional parameter that is coming from the nonlinear theory. We employ the causality and unitarity principles to identify an upper bound for this free parameter. The effects of this parameter on the physical properties of the black hole solution are investigated.
