利用局部渐近平坦时空的重整化边界应力张量，研究了五维黑色物体的性质。这提供了准局部形式的一种更精细的形式，这对于渐近平坦重力的全息解释是有用的。我们应用这一技术研究了黑洞、黑环和黑弦的热力学性质。使用这种方法的优点是我们可以超越“细环”近似，计算任何一般(薄的或胖的)黑环解的边界应力张量。我们认为，边界应力张量编码了区分具有不同视界拓扑的黑色物体所需的信息。我们还详细地研究了Susy Black环，阐明了渐近电荷与视界上定义的电荷之间的关系。此外，我们还得到了“薄”偶极黑环的平衡条件。
We study the properties of five-dimensional black objects by using the renormalized boundary stress tensor for locally asymptotically flat spacetimes. This provides a more refined form of the quasilocal formalism, which is useful for a holographic interpretation of asymptotically flat gravity. We apply this technique to examine the thermodynamic properties of black holes, black rings and black strings. The advantage of using this method is that we can go beyond the ‘thin ring’ approximation and compute the boundary stress tensor for any general (thin or fat) black ring solution. We argue that the boundary stress tensor encodes the necessary information to distinguish between black objects with different horizon topologies in the bulk. We also study in detail the susy black ring and clarify the relation between the asymptotic charges and the charges defined at the horizon. Furthermore, we obtain the balance condition for ‘thin’ dipole black rings.
