论文摘要
D. Glavan和C. Lin [Phys。莱特牧师。 124，081301（2020）]，旨在绕过Lovelock定理，并对四维引力动力学产生非平凡的贡献。但是，该理论的有效性和一致性最近受到质疑。我们研究了新型的四维爱因斯坦 - 高斯 - 摩托克重力中，由出生的污染电场收取的静态和球形对称的黑洞。发现黑洞解决方案仍然遭受奇异性问题的侵害，因为来自无穷大的粒子可以达到奇异性。还证明，在这个新的引力理论中，出生的带电的黑洞可能优于麦克斯韦指控的黑洞，是Schwarzschild-ads-Ads样黑洞的带电扩展。还分析了黑洞溶液的一些基本热力学。此外，我们还恢复了H.lü和Y. Pang提出的正规化的四维爱因斯坦 - 加斯 - 鲍斯 - 邦网的重力[Arxiv：2003.11552]。
A novel four-dimensional Einstein-Gauss-Bonnet gravity was formulated by D. Glavan and C. Lin [Phys. Rev. Lett. 124, 081301 (2020)], which is intended to bypass the Lovelock's theorem and to yield a non-trivial contribution to the four-dimensional gravitational dynamics. However, the validity and consistency of this theory has been called into question recently. We study a static and spherically symmetric black hole charged by a Born-Infeld electric field in the novel four-dimensional Einstein-Gauss-Bonnet gravity. It is found that the black hole solution still suffers the singularity problem, since particles incident from infinity can reach the singularity. It is also demonstrated that the Born-Infeld charged black hole may be superior to the Maxwell charged black hole to be a charged extension of the Schwarzschild-AdS-like black hole in this new gravitational theory. Some basic thermodynamics of the black hole solution is also analyzed. Besides, we regain the black hole solution in the regularized four-dimensional Einstein-Gauss-Bonnet gravity proposed by H. Lü and Y. Pang [arXiv:2003.11552].
