We obtain the isoperimetric profile for the standard initial slices in the Reissner–Nordstrom and Schwarzschild anti-de Sitter spacetimes, follow- ing recent work of Bray and Morgan on isoperimetric comparison. We then discuss these results in the c
我们研究了一个极端的Kerr-Sen黑洞周围两个不带电的旋转粒子的碰撞,并计算了通过超级Penrose过程从Kerr-Sen黑洞中提取能量的最大效率。 我们考虑两个质量粒子的碰撞以及无质量粒子与质量粒子的碰撞。 我们计算了所有情况的最大效率,发现效率随着Kerr-Sen黑洞参数($$ b = 1-a $$ b = 1-a)减小而增加。
