Angular momentum surface density of the kerr metric Fernández Jambrina, L. Chinea Trujillo, Francisco Javier A method for interpreting discontinuities of the twist potential of vacuum stationary axisymmetric solutions of Einstein's equations is introduced. Surface densities for the angular momentum of the source can be constructed after solving a linear partial differential equation with boundary conditions at infinity. This formalism is applied to the Kerr metric, obtaining a regularized version of the density calculated with other formalisms. The main result is that the integral defining the total angular momentum is finite for the Kerr metric. 2023-06-20T19:16:50Z 2023-06-20T19:16:50Z 2023-06-20T19:16:50Z 1993-10-18 journal article https://hdl.handle.net/20.500.14352/59474 0031-9007 10.1103/PhysRevLett.71.2521 eng PB89-0142 open access American Physical Society
