论文摘要
我们研究了爱因斯坦 - 马克斯韦尔系统中松散捕获的表面（LTS）和动态横向捕获表面（DTT）的特性。目前的四位作者提出了这些表面的概念，以表征强力区域。我们证明了LTSS/DTTS区域的penrose样不平等现象。有趣的是，尽管该区域的天真预期的上限是具有相同质量和电荷的Reissner-Nordstroem黑洞的光子球的，但所获得的不平等包括由电磁场的能量密度或压力/张力表示的校正。由于这种校正，LTS区域的penrose样不等式比天真的预期更紧密。我们还在Majumdar-Papapetou两个黑洞空间中以数值评估校正项。
We study the properties of the loosely trapped surface (LTS) and the dynamically transversely trapping surface (DTTS) in Einstein-Maxwell systems. These concepts of surfaces were proposed by the four of the present authors in order to characterize strong gravity regions. We prove the Penrose-like inequalities for the area of LTSs/DTTSs. Interestingly, although the naively expected upper bound for the area is that of the photon sphere of a Reissner-Nordstroem black hole with the same mass and charge, the obtained inequalities include corrections represented by the energy density or pressure/tension of electromagnetic fields. Due to this correction, the Penrose-like inequality for the area of LTSs is tighter than the naively expected one. We also evaluate the correction term numerically in the Majumdar-Papapetrou two-black-hole spacetimes.
