在轴对称时空中,彭罗斯不等式可以得到加强以包含角动量。我们证明了最小表面不等式的一个版本,更准确地说,是根据最小表面面积、角动量和表面尺寸的特定度量来证明 ADM 质量的下界。我们考虑轴对称且渐近平坦的初始数据,并沿逆平均曲率流使用 2 曲面上 Geroch 准局域能量的单调性。
In axially symmetric spacetimes the Penrose inequality can be strengthened to include angular momentum. We prove a version of this inequality for minimal surfaces, more precisely, a lower bound for the ADM mass in terms of the area of a minimal surface, the angular momentum and a particular measure of the surface size. We consider axially symmetric and asymptotically flat initial data, and use the monotonicity of the Geroch quasi-local energy on 2-surfaces along the inverse mean curvature flow.
