论文摘要
我在三维HORAVA重力中重新访问旋转的黑洞溶液，Z = 2作为更简单的可重新分解量子重力的设置。与三维爱因斯坦重力中的黑洞不同，该溶液在原点上具有曲率奇异性，用于非变化旋转参数J。对于反DE的保姆空间，与往常一样，有黑洞事件的视野，与宇宙审查制度一致。另一方面，对于平坦或De Sitter空间，较早的解决方案也存在宇宙审查的问题，因为没有像爱因斯坦重力那样具有常规的黑洞地平线，除了通常的宇宙学范围外，对于后一种情况，因此可以在Horava Gravity中裸露奇异性。但是，在最近的校正的帮助下，我表明该解决方案在起源上具有奇特的黑洞地平线，因此即使没有lorentz侵入的高衍生术语，即使没有扁平或de Sitter的常规黑洞地平线也不是赤裸裸的。另一方面，我还注意到，由于较高的衍生物和角度摩托屏障的结合影响，与通常的智慧相反，与通常的智慧相反，即使是平面案例，也存在新的``宇宙学的视野。洛伦兹侵入重力。
I revisit rotating black hole solutions in three-dimensional Horava gravity with z = 2 as a simpler set-up of the renormalizable quantum gravity `a la Lifshitz and DeWitt. The solutions have a curvature singularity at the origin for a non-vanishing rotation parameter J, unlike the black holes in three-dimensional Einstein gravity. For anti-de Sitter space, there are black hole event horizons as usual and the singularity is not naked, in agreement with the cosmic censorship. On the other hand, for flat or de Sitter space, the earlier solution has also a cosmic-censorship problem because there are no conventional black hole horizons as in Einstein gravity, other than the usual cosmological horizon for the latter case, so that the singularity could be naked in Horava gravity. However, with the help of recent corrections, I show that the solutions have a peculiar black hole horizon at the origin so that the singularity is not naked even without the conventional black hole horizons in flat or de Sitter case, due to the Lorentz-violating higher-derivative terms. On the other hand, I note also that a new ``cosmological" horizon exists even for the flat case, contrary to the usual wisdom, due to combined effects of the higher derivatives and the angular-momentum barrier. I study an unified treatment of their unusual black hole thermodynamics for the flat and de Sitter spaces, as well as the anti-de Sitter space, which might be due to lack of the absolute horizons in the Lorentz-violating gravity.
