我们引入一个新的时间无关的家庭的克尔时空代表旋转黑洞的分析坐标系。我们还提出了一个(2 + 1)+1形式的喇叭形几何的特征。应用这种形式主义,我们的新家庭的坐标系,我们确定,第一次,分析和固定喇叭片一般旋转黑洞,甚至带电黑洞的存在下的宇宙常数。我们目前的结果度量函数在此切片和分析的几何形状的旋转喇叭表面。
We introduce a new time-independent family of analytical coordinate systems for the Kerr spacetime representing rotating black holes. We also propose a (2+1)+1 formalism for the characterization of trumpet geometries. Applying this formalism to our new family of coordinate systems we identify, for the first time, analytical and stationary trumpet slices for general rotating black holes, even for charged black holes in the presence of a cosmological constant. We present results for metric functions in this slicing and analyze the geometry of the rotating trumpet surface.
