论文摘要
众所周知，（$ 2+1 $）充电的BTZ（Banados，Teitelboim，Zanelli）黑洞可以被带电的标量场和带电的粒子（相比之下）（$ 3+1 $）和更高的尺寸和更高的尺寸相比。在这方面，更深入地了解Einstein-Gauss-Bonnet（EGB）重力的（$ 2+1 $） - 尺寸充电的黑洞的性能可能会发挥重要作用。在本文中，我们测试了Henniger等人最近得出的新型EGB理论中（$ 2+1 $）的弱宇宙审查猜想的有效性。 Al（2021）。我们表明，在EGB重力中，粒子在地平线上可能具有的最小能量对于极端和几乎超级BTZ黑洞都会产生负数。事实证明，在EGB理论中，极端和几乎超级$（2+1）$尺寸BTZ黑洞都可以过多地充电，从而违反了弱宇宙审查猜想（WCCC）的行为，这与经典BTZ黑洞获得的结果非常吻合。
It is well known that ($2+1$) dimensional charged BTZ (Banados, Teitelboim, Zanelli) black hole can be overcharged by a charged scalar field and a charged particle in contrast to their analogues in ($3+1$) and higher dimensions. In this regard, it may play an important role to understand more deeply the properties of the ($2+1$)-dimensional charged black hole in the Einstein-Gauss-Bonnet (EGB) gravity. In this paper, we test the validity of the weak cosmic censorship conjecture for the ($2+1$)-dimensional charged black hole in novel EGB theory derived recently by Henniger et. al (2021). We show that the minimum energy that particle can have at the horizon becomes negative for both an extremal and nearly-extremal BTZ black holes in EGB gravity. It is proven that both extremal and nearly-extremal $(2+1)$ dimensional BTZ black hole could be overcharged in EGB theory, leading to the violation of the weak cosmic censorship conjecture (WCCC), which is in good agreement with the results obtained for the classical BTZ black hole.
