We show explicitly, for different types of extremal black holes, that test fields satisfying the null energy condition at the event horizon cannot violate the weak cosmic censorship conjecture. This is done by checking, in each case, that the hypotheses for the general theorem in [7] are satisfied.

几个极值黑洞弱宇宙审查猜想的证明

我们明确表明，对于不同类型的极值黑洞，满足事件视界零能量条件的测试场不会违反弱宇宙审查猜想。这是通过在每种情况下检查是否满足 [7] 中的一般定理的假设来完成的。
