论文摘要
我们提出了代数D型的完整黑洞空位的完整家族的改进的度量形式,包括任何宇宙常数。 Debever于1971年,Plebanski和Demianski于1976年发现了这一班级,并在2005年由Griffiths和Podolsky方便地重新构建。在我们的新形式中,该指标的新形式被简化,部分分解,完全分解且完全阐明。它们取决于具有直接物理含义的七个参数,即M,A,L,Alpha,E,G,Lambda,这些参数分别表征了质量,Kerr样旋转,螺母参数,加速度,黑洞的电荷和宇宙常数。此外,该通用度量直接减少到熟悉的(可能加速的)Kerr-Newman-(抗)de Sitter时空的形式,充满了充电的taub-nut-(抗)de Sitter溶液,或者(可能仅将相应的参数设置为零),或(可能旋转和带电的)C-Metric。此外,它表明plebanski-demianski家族不涉及加速黑洞,而没有kerr样旋转。新的改进的度量标准还使我们能够研究各种物理和几何特性,即奇异性的特征,两个黑洞和两个Cosmo-acceleration Horizons(在一般情况下),相关的台币,全球结构,包括Penrose共生图,造成宇宙的参数,贯穿了宾夕法尼亚州的参数,策划了黑孔,旋转的范围,这些条件是旋转的,这些条件是旋转的,这些序列是旋转的,旋转了旋转的旋转,,旋转了旋转,,旋转了旋转的范围,,旋转了旋转的旋转,,旋转了旋转,,旋转了旋转的旋转,,旋转了旋转的范围。热力学量。
We present an improved metric form of the complete family of exact black hole spacetimes of algebraic type D, including any cosmological constant. This class was found by Debever in 1971, Plebanski and Demianski in 1976, and conveniently reformulated by Griffiths and Podolsky in 2005. In our new form of this metric the key functions are simplified, partially factorized, and fully explicit. They depend on seven parameters with direct physical meanings, namely m, a, l, alpha, e, g, Lambda which characterize mass, Kerr-like rotation, NUT parameter, acceleration, electric and magnetic charges of the black hole, and the cosmological constant, respectively. Moreover, this general metric reduces directly to the familiar forms of (possibly accelerating) Kerr-Newman-(anti-)de Sitter spacetime, charged Taub-NUT-(anti-)de Sitter solution, or (possibly rotating and charged) C-metric with a cosmological constant by simply setting the corresponding parameters to zero. In addition, it shows that the Plebanski-Demianski family does not involve accelerating NUT black holes without the Kerr-like rotation. The new improved metric also enables us to study various physical and geometrical properties, namely the character of singularities, two black-hole and two cosmo-acceleration horizons (in a generic situation), the related ergoregions, global structure including the Penrose conformal diagrams, parameters of cosmic strings causing the acceleration of the black holes, their rotation, pathological regions with closed timelike curves, or thermodynamic quantities.
