On the BTZ Black Hole and the Spinning Cosmic String
Abstract
We reviewed the Ba\u nados-Teitelboim-Zanelli (BTZ) black hole solution in connection with the spinning string solution. We find a new exact solution, which can be related to the $(2+1)$-dimensional spinning point particle solution. There is no need for a cosmological constant, so the solution can be up-lifted to $(3+1)$ dimensions. The exact solution in a conformal invariant gravity model, where the spacetime is written as $g_{μν}=ω^2 \tilde g_{μν}$, is horizon free and has an ergo-circle, while $\tilde g_{μν}$ is the BTZ solution. The dilaton $ω$ determines the scale of the model. In accordance with the spinning cosmic string solution, it is conjectured that the new solution can be linked to the mass of the interior of the spinning cosmic string.
